I need help with tracking
Ok the video that you can see on my youtube is the one I need help with. The video is actually in 1080p and I have no idea why it is showing in such a low resolution, but that is not the problem. I need to track the gun and add a null to that track, after that I want to add a red solid layer and bring down its opacity a little, to simulate a laser sight from the gun.Then I tried to parent and SHIFT parent the red solid to the track, the end product would have to look like what you can see in the picture. I have watched a TON of videos about tracking and just can not the the result I need. the laser needs to follow the gun as I aim up and bring the gun down. How should I do this.......? Please someone help or link me a tutorial that will be helpful.....
You have a couple of problems. First you don't need to use shift parent, just parent. Second, your red solid is a 3D layer and you have applied 2D tracking info to the solid. Actually, there's another mistake and it is in the tracking. You should also be tracking scale because the gun moves from left to right as well as up and down. This changes the distance between the front and back tracking points.
My workflow with this project would be:
Track Motion of the front and back of the gun including position, scale and rotation
Apply the track info to a null called GunTrack or something like that
Add a solid and apply the beam effect or mask the red solid to simulate the shape of a laser sight
Change the blend mode of the solid to ADD
Move the anchor point to the center of the starting point of the laser
Parent the solid to the Gun Track null
That should do it.

I just downloaded an album from itunes and 2 of the tracks will not play at all, they cut off. I need help with this??
Does the track play correctly in Quicktime Player? If it does then it is an iTunes issue. If it doesn't then it is possible the file was not completely downloaded, or is corrupt.

Need help with almost completed plugin engine project
Hi all,
For a while now I have been working on a plugin engine. After a few iterations, the engine is similar to the Eclipse engine, in that plugins use extension points and extensions to allow contributions. Unlike the eclipse engine I have added the ability for plugins to fire events through the engine and other plugins can add listeners, all through the plugin.xml manifest. Dependencies are mostly handled automatically at plugin load time (when extensions get resolved to extension points, and listeners get resolved to events). For the case where a plugin needs to use classes from another plugin, dependencies are also allowed to be declared. Like the eclipse engine, activation of plugins occurs the first time a class is used within the plugin's classpath, OR a plugin can be activated after it is loaded.
What I need help with is testing, working on examples to provide with the engine project, and feedback/suggestions before we release the M1 build. I am asking for those that are interested in this type of work to volunteer to help where applicable and possible. I want to provide a solid plugin engine to the java community, one that is easy to use, works well, and is pretty effecient in terms of resource usage and performance.
Of particular interest to me right at the moment is dealing with multiple versions. As I see it, the engine will be used within an application and as such plugins would be distributed with a specific application version. The plugin version itself is more of a notification as to what version a plugin is, although I imagine it will help when updating at runtime as well.
Just a few other details of the engine. It handles (or will soon) dynamic load, unload and reload of plugins at runtime. Plugins can be distributed in an archive file format, we call .par (Plugin ARchive), with additional plugin filename extensions configurable at runtime. The plugins can be developed and deployed in an expanded directory format as they are in Eclipse as well, or in the archive format. In the archive format they do not need to be unzipped when deployed, and they can contain embeded jar/zip libraries. The engine handles finding and creating classes directly out of the .par file at runtime.
Multiple locations to find plugins are configurable before the engine starts, and even after it starts more could be added to allow additional locations to find plugins. URLs are supported, and soon the HTTP protocol will be supported so that plugins can be downloaded and installed at runtime.
The project can be found at www.sourceforge.net/projects/genpluginengine. If you would like to get involved and help out, please sign up on the dev mail list and send an email to introduce yourself to the rest of the members on the list.
I'll also add that I am working on a Swing UI Framework built entirely from plugins. It provides a ready-to-launce UI application that developers can simply add their plugins to, extending various extension points of the framework to have menu items, toolbar buttons, status bar access, help and preferences dialog additions, file i/o choosers, tons of open-source components ready to use (or extend to add on to), and like Eclipse, hopefully... draggable window frames that can be dropped on any other frame to form a tabbed frame of windows. Some of this is a ways off, some is getting there now. Presently you can add menu items that do allow plugin activation when first clicked, so plugins can be loaded but not activated until needed. The Preference dialog works but is not completed, and a plugin that adds a plugin control panel to view all loaded plugins, activate them, load/unload/reload, view extension points, extensions, dependencies, etc is partially completed. The point is, to allow a ready to run UI framework in Swing with an easy path for developers to quickly build applications with. If you are interested in this, when you join the mail list and introduce yourself, indicate that you are interested in this as well, as we need help with plugin development for it and would appreciate more help here too.
Look forward to some replies.Might I suggest setting up a project at a known project-site? I've seen your progress and questions posted here from time to time, but one of the drawbacks is that you have to fill each post with the entirity of your vision to explain what you're doing. That's a lot of text to read - and most folks will skip right over it.
On the other hand, a well-crafted, good-looking project web-site, with appropriate links and docs and vision statements, diagrams, etc. will have more likelyhood of attracting volunteers. java.net and sourceforge.net are likely spots to set up shop. In addition, you get CVS and bug-tracking systems, which can be quite valuable in such a large-scale project where there are lots of pieces. -
Need help with some rules. I want to book a number to a specific Entity at a Specific Custom 4 only. I don't want this formula to work at all C4 levels. How can this be done?
for example if Entity is "XBM1123" and we use C4 for tracking and the tracking level I want to book it to is IMPORT, how can this be done for a specific account 4400221
I have my formula as
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" or HS.Custom4.Member = "IMPORT" then
HS.EXP "A#4400221= A#4521111 + A#3526644 + A#635210"
End If
End if
this did not work. I got hte following error
Calculate started.<BR>Error executing VBScript Microsoft VBScript runtime
error, Line 259:Object doesn't support this property or method:
'HS.Custom4.Member'.<BR>Calculate finished.<BR>Error executing
VBScript %0.
I then changed it to the below and it still did not work
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" then
HS.EXP "A#4400221.C4#IMPORT= A#4521111 + A#3526644 + A#635210"
End If
End if
error
Invalid Custom1 member
specified for this function.
Invalid Destination specified for this function:
A#4400221.C4#IMPORT.You are close.
Try:
If pov_value = "<Entity Currency>" or pov_value = "<Entity Curr Adjs>" Then
If HS.Entity.Member = "XBM1123" then
HS.EXP "A#4400221.C4#IMPORT= A#4521111.C4#IMPORT + A#3526644.C4#IMPORT + A#635210.C4#IMPORT"
End If
End if
or replace IMPORT with with Top_C4 or what ever member you need to copy to C4#IMPORT.
Rule of thumb, to be on the safe side and for most simple calcs, is if you mention a dimension on the left side, you need to define it on the right side as well. -
Need help with flash player installation please !!!!
Hello,
I need help with my flash player installation because every time I access a movie this is the message I receive.
This content on Xfinity TV is not available for viewing with Chrome's "Incognito" mode. To play this video using Chrome, please view this page without "Incognito" mode.
Still having problems? Try resetting your Flash player license.Incognito mode is a Google Chrome setting when you open a new window (Cmd+Shift+N on a Mac Ctrl+Shift+N on Windows) It opens a "private" window with no cookies and no tracking. The problem with it is that when you disable cookies, your license files are not sent to the site (whetehr it's YouTube or xFinity or any other that uses license files for paid content) and it treats you as if you're a first time visitor. Paid videos won't play wihtout the cookies sending the license file info.
This isn't a Flash Player setting. It's in Chrome. I did some research and according to Google, "Incignito" mode is off by default, and can ONLY be activate by the keyboard shortcut. There IS a way to disable it from the registry http://dev.chromium.org/administrators/policy-list-3#IncognitoModeAvailability -
Need Help with Inserting Timeline Markers
Friends,
I have not use my premiere element 3.2 since 2008 and forgot some of the procedures. now, I need help with the insertion of Timeline Markers. I did what the Help Page showed me. But the markers were not effective in the resulting DVD, or, even when viewing the video in the editing page as if thye were not there! Here is what I did:.
1) Click the Timeline button.
2) Click in an empty space in a video or audio track in the Timeline to make the Timeline active and deselect any clips.
3) Move the current-time indicator in the Timeline to the frame where I need the marker.
4) Click the Add Marker icon in the Timeline to place the Marker 5 times where I want them.
5) Verified that each Timeline Marker is present at the intended place.
6) Burned DVD
7) Can NOT jump to any of the intended Marker in the Resulting DVD during playback.
The question is "What did I do wrong or didn't do?" It seems that I did the same before and worked! Please advise!
Also, what are the significance of the Red line just below the Timeline and the yellow bars inside the video and audio frames. But after preforming Timeline/Render Work Area, they were all gone? What purposes do they serve and what is the significance of Rendering? Thank you for your help!
I repeat the process and did a Rendering before making the DVD also. It did not help!
Andy LimSteve,
Long time no talk! You used to help me out many times when the PE-1 through PE-3 came out. I was HOPING you would still be around and you are! You came through again this time! Many thanks to you.
I use the Add DVD Scene button to insert the Markers. They are Green. Made a DVD and the markers work OK although ythey are "effective" during play back using the editing window.
While that problem was solved, will you come back and answer the other two questions concerning Rendering and the Red/Yellow lines? I would appreciate it very much!
Andy Lim

But... I didn`t understand the first partSorry, what part is that? You probably understood "Welcome to the forum!" It looks like you understood most of what I said, perhaps before I said it. You seem to be on the right track.
Unlike talking to a co-worker in the next cube, exchanging messages with someone on this forum takes a fair amount of time, so it's worth the time it takes to explain things very clearly, more than you would in conversation. Post all the relevant information, and say exactly what the problem is.
amm i tried to do this:
select t_recipes.recipe_name, count(t_cooking_mode.cooking_mode)
from (t_cooking_mode INNER JOIN t_integration ON t_cooking_mode.recipe_no = t_integration.recipe_no )
INNER JOIN t_products ON t_integration.product_no = t_products.product_no)
WHERE t_products.product_name = 'tomatoes'
GROUP BY t_recipes.recipe_name
help?Please help by posting whatever you know about the problem. For example, if there's a error message, post the complete error message, including the line number.
Help the people who want to help you by formatting your code and making it easy to read and understand. This will help you, too.
For example, here's exactly what you posted, with only the white-space changed to make parallel items, such as parentheses, line up nicely:
select t_recipes.recipe_name
, count(t_cooking_mode.cooking_mode)
from ( t_cooking_mode
INNER JOIN t_integration ON t_cooking_mode.recipe_no = t_integration.recipe_no
INNER JOIN t_products ON t_integration.product_no = t_products.product_no
WHERE t_products.product_name = 'tomatoes'
GROUP BY t_recipes.recipe_nameWhen you format your code like this, it can be very easy to spot errors like unbalanced parentheses. In this case, the ')' right before the WHERE clause has no matching '('. You don't need to use any parentheses at all in the FROM clause. You can simply say:
FROM t_cooking_mode
JOIN t_integration ON t_cooking_mode.recipe_no = t_integration.recipe_no
JOIN t_products ON t_integration.product_no = t_products.product_no
WHERE ...INNER JOIN is the default kind of join, which makes sense, since the majority of all joins are inner joins. I usually say JOIN (instead of INNER JOIN) because it makes the code more compact and easier to read (at least for me), but I won't be maintaining your code, so do what's best for you.
What are you trying to find in this problem? Is it a recipe name or a cooking mode? If it's a cooking mode, the why do you have t_recipes.reciple_name in the SELECT (and GROUP BY) clause? Shouldn't you be using some other column, from some other table?
If I understand the problem correctly, the t_recipes table is not needed in this problem. You won't necessarily use every table in every query.
When you post formatted text on this site, type these 6 characters:

Need help with a currently "in-use" form we want to switch to Adobes hosting service
Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")

Phenix City, Alabama 36869Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

Need help with trim and null function
Hi all,
I need help with a query. I use the trim function to get the first three characters of a string. How do I write my query so if a null value occurs in combination with my trim to say 'Null' in my results?
ThanksHi,
Thanks for the reply. What am I doing wrong?
SELECT trim(SUBSTR(AL1.user_data_text,1,3)),NVL
(AL1.user_data_text,'XX')
FROM Table
I want the XX to appear in the same column as the
trim.The main thing you're doing wrong is not formatting your code. The solution may become obvious if you do.
What you're saying is:
SELECT trim ( SUBSTR (AL1.user_data_text, 1, 3))
, NVL ( AL1.user_data_text, 'XX' )
FROM Tablewhich makes it clear that you're SELECTing two columns, when you only want to have one.
If you want that column to be exactly like the first column you're currently SELECTing, except that when that column is NULL you want it to be 'XX', then you have to apply NVL to that column, like this:
SELECT NVL ( trim ( SUBSTR (AL1.user_data_text, 1, 3))
, 'XX'
FROM Table -
I need help with resetting my ichat. When i try to login now it wont let me... it says "AOL Instant Messenger password" and then "iChat can't log in to ... because your login ID or password is incorrect. How do I reset this if I cant log in? When I try to press online the same thing pops up and I have no way of logging in or asking for help.
Hi,
iChat (it would help to know which version) can accept Apple IDs as valid AIM Screen Names.
However if you have iChat 5 or earlier you cannot use ones ending in @me.com or @icloud.com issued by iCloud. (they can be used in iChat 6 or Messages as these versions make a double login to AIM and Apple to allow the use of the password).
In addition if you are using an Apple ID for an AIM Screen Name the password still needs to keep to the 16 character limit that AIM has.
AN @mac.com name can be used on any version of iChat (Until the 30th June 2014)
As it does not need a double check with Apple you can use it to log in to the AIM Web pages
Login here with an AIM Name registered at AIM or and @mac.com name and see if you get any suspended account messages.
Sometimes account can be suspended. Usually because something has triggered the "Unusual Activity" item.
About a year ago many @mac.com users that travelled out of their own country found themselves suspended when they got home.
If the Name checks out of if an Apple ID the password in known to be 16 characters or Less then do this:-
In Lion upwards open a Finder Window and use the Go Menu whilst holding down the ALT key.
Select the Library that appears in the menu list.
Navigate to Preferences.
(If you have version earlier than Lion the just navigate to ~/Library/Preferences (that's the Library in you Home - Little House icon - folder)
Fnd com.apple.ichat.aim.plist (even if you are using Messages)
Drag the file to the Trash and Restart the app.

Need help with Airport Express and so on.
Ok so my main problem before getting into what I need help with here is that our MacBooks and now my iPhone 6 plus isn't staying online. Keep getting booted off and then I either have to select the network again or it will eventually go back on. If anyone has a solution or so please feel free to answer that as well. I'm running on Roadrunner with a Netgear 600 wireless router and a motorola modem. Both of which I'll leave the link to below for a better look.
My Main Question: So I'm looking at a new wireless router mainly and possibly a new modem. I know Apple products are trustworthy but how good is the Airport Express and other Airport products. Also what is the Maximum speed and Maximum data speed for the cheapest express station and if anyone knows the speeds of the other devices it would be greatly appreciated.DSL Router to Netgear 5-port Switch and I used the switch to connect to Airport Extreme, TV, Blue-Ray DVD player and DirecTV Receiver.
The AirPort Extreme base station (AEBS) is a router so it will do what you need.
You need to reconfigure your setup. Connect the WAN port of the AEBS to the DSL router. Then connect the Netgear switch to one of the LAN ports on the AEBS. The AEBS will properly share the connection. -

I need to find the greatest grant year for the grant by a period parameter.
once i find the greatest year i need to check the value of period 14 for that grant for the previous year and add it to the budget amount for that grant. however if their is an entry in the greatest year for period 00 then i need to ignore the period 14 of previous year and do this calculation current period +(current period - greatest year 00)
hope that makes sense so in other words with the new data above. if i was querying period two of grant year 11. i would end up with $800
because the greatest year is 11 it contains a period 0 with amount of $400 so my total should be
period 2 amount $ 600
period 0 amount $ 400 - period 2 amount of $600 = 200
600+200 = $800
if i query period 1 of grant 360055 i would just end up with 800 of grnt year 10.
i have tried to modify that query you supplied to me with no luck. I have tried for several day but im embarrased to say i just can get it to do what im trying to do .
can you please help me out.
here is the query supplied by frank kulash who gracefully put this together for me.
WITH got_greatest_year AS
SELECT fgl.* -- or whatever columns are needed

AND fgl_period = :given_period
OR ( fgl_grnt_year = greatest_year - 1
AND fgl_period = 14
;MiguelHi, Miguel,
Are you waying that, when the greatest year that has :given_period also has period='00' (or '0', or whatever you want to use), then you want to double the budget from the given_period (as well as subtract the budget from the '00', and not count the pevious year's '14')? If so, add another condition to the CASE statement which decides what you're SUMming:
WITH got_greatest_year AS
SELECT TO_NUMBER (fgl_grnt_year) AS grnt_year
, fgl_period
, TO_NUMBER (fgl_budget) AS budget
, MAX ( CASE
WHEN fgl_period = :given_period
THEN TO_NUMBER (fgl_grnt_year)
END

SELECT grnt_year

WHEN grnt_year = greatest_year
AND fgl_period = '00'

END
) OVER () AS cnt_00

Need Help With File Matching Records
I need help with my file matching program.
Here is how it suppose to work: FileMatch class should contain methods to read oldmast.txt and trans.txt. When a match occurs (i.e., records with the same account number appear in both the master file and the transaction file), add the dollar amount in the transaction record to the current balance in the master record, and write the "newmast.txt" record. (Assume that purchases are indicated by positive amounts in the transaction file and payments by negative amounts.)
When there is a master record for a particular account, but no corresponding transaction record, merely write the master record to "newmast.txt". When there is a transaction record, but no corresponding master record, print to a log file the message "Unmatched transaction record for account number ..." (fill in the account number from the transaction record). The log file should be a text file named "log.txt".
Here is my following program code:

I am not sure what is wrong with my code above to make my results different from the correct results.
Much help is appreciated. Please help.From the output, it looks like one problem is just formatting -- apparently you're including a newline in log entries and not using tabs for the newmast output file.
As to why the numbers are off -- just from glancing over it, it appears that the problem is when you add multiple transaction values. Since account.combine() is so simple, I suspect that you're either adding creating transaction objects incorrectly or not creating them when you should be.
Create test input data that isolates a single case of this (e.g., just the Mary Smith case), and then running your program in a debugger or adding debugging code to the add/combine method, so you can see what's happening in detail.
Also I'd recommend reconsidering your design. It's a red flag if a class has a name with "Create" in it. Classes represent bundles of independant state and transformations on that state, not things to do.
