Keeping a cell empty

I would like to keep cells without any information empty and not filled up with "0". At the moment, I write a number in a chart and that number is forwarded in another chart. It work OK, but if in one of the cell, it is empty ( no number), then it is forwarded as " 0 " in the other chart. The problem is that in the graft that is related to the second chart, the values will be display in a jigsaw fashion. When it is empty in the first chart, I will like the graft to ignore the value and not display the " 0 ".
I was told to use a formula like :
=RECHERCHEV($A3;Poids des spécimens :: $A$2:$I$14;4;FAUX);Stats::A2=SI(Data :: A2=0,"",Data :: A2) but it does not work...
I went 3 times to a " one to one " session to no avail. Thank you very much.

Hi,
Welcome to Apple Discussions and the Numbers '08 forum.
Looking at your formula(s), I think you got good advice, but that how to implement the solution wasn't made clear. What you're trying to do here is to place a zero length text string in the cell if the value that would go there is zero. The graph will ignore the text value in that cell and not include it in the graph. Here's the formula above with the English names for the functions (and a shorter name for the first table), mostly for my own benefit in reading it.
=VLOOKUP($A3,Poids::$A$2:$I$14,4,exact_match),Stats::A2=IF(Data::A2=0,"",Data::A 2)
This is actually two formulas.
=VLOOKUP($A3,Poids::$A$2:$I$14,4,exact_match)
uses the value in A3 of the table containing the formula as a search value. It looks for an exact match of that value in cells A2 to A14 of the table "Poids". If the value is found, the formula returns the value in the cell in column D (the 4th column of the lookup table) of the same row as the search value was found (eg. if the search value is found in A13, the value in D13 is returned). If an exact match of the value is not found (eg. if the spelling of the specimen name in A3 differs from the spelling in the Poids table), an error message, "VLOOKUP couldn't find the requested value" is returned.
Stats::A2=IF(Data::A2=0,"",Data::A2)
If I'm reading this correctly, the formula is:
=IF(Data::A2=0,"",Data::A2)
and it is located in cell A2 of the Stats table.
That brings up some possible overwrite issues as the formulas are filled down their respective columns, but I'll leave comment on those pending some clarification of which table is used to generate the graph, and the purpose of each of the other tables. My current image of the document is a bit blurry.

So I am trying to empty my trash but something is keeping it from emptying - I think it's this file: SONYCOPY.IND an executable unix file that I know nothing about - so nothing else will delete either

So I am trying to empty my recycle bin but something is keeping it from emptying - I think it's a unix file called SONYCOPY.IND? Now the trash is also creating new folders with recovered items? Not sure what's going on...

That file could be set as a Launch Agent or Daemon in your ~/Library or /Library, You could try to look for it or Safeboot your computer and then empty the trash. Safebooting disables Launch Agents/Daemon and Third Party Kernal extensions. Here's the article to Safeboot OS X: What is Safe Boot, Safe Mode? - Apple Support

Why does iTunes keeps coming up empty even after successfully restoring from a previous library?

So, the other day, I opened up iTunes to find that all of my music and movies (all media at all) was gone. Well, darn. I looked in my previous saved libraries and the most recent file was from a minute or so before I discovered the problem - so, an empty library. Awesome. Next, I tried a system restore as my computer had recently installed some updates and I wasn't sure if that might or might not have effected this in anyway (I'm not the most tech-savvy person in the world). Successfully did that, but to no avail. So, I went back to my previous iTunes libraries again and the next most recent one was from last November. ****. Well, I figured, that's the best I can do. So I tried that.
Ok, so I had a library from a while ago, missing everything I'd added since November, but I still had all the files on my computer so I figured, I'll just go and add everything again. This was going to be a long and boring process as I had spent a lot of time in iTunes adding song details and album art and making playlists, etc, plus re-downloading everything new from the iTunes store on my slow connection would literally take weeks. But, I figured, I didn't have much of a choice.
So a few days passed, things went along normally, I shut down and started up my computer normally a few times, always checking iTunes with no change at all. Then, yesterday, I opened iTunes up in the afternoon and that same restored (from November) library was there, but I left for a few hours, not shutting down my computer, came back and everything was gone again.
Ahhh, just thinking of this now, I should mention that I'm running iTunes 10.7.0.21 because I hate iTunes 11... now I'm wondering, would this cause me to have the problems that I'm having?
Everyone's been telling me just to re-import everything and that it's no big deal, but I don't want to go through the process of re-importing and re-downloading and reorganizing 3500 media files if they're all just going to disappear again!

Wow, this is just what i DO want to happen!
What do you use? I heard that LimeWire does this with iTunes on a Mac, but couldn't get it to work in this way on a PC...
Glad you sorted it out though.

My superdrive keeps ejecting even empty.

My supredrive keeps ejecting without having any disc in.
I also figured that everytime the mac feels a hit around it or in the keyboard... like a hard one...
then u can hear the superdrive ejecting.

Keep current cell boarders -- Report Generation Toolkit

I have a template in excel and I am using the Excel Easy Table.vi in order to write a string array to the report. The issue I'm running into is, because it's a template, I already have the boarders formatted the way I want within Excel, but when I write the table it doesn't keep the boarders. Is there any way I can either:
1. Get boarder formatting then set the formatting back to that
2. Stop formatting the boarder in the first place

Any reason why I keep having to empty the trash twice?

I'm not talking about attempting to trash something that requires a log out before it can be disposed of, but just general things, old apps, zip files, etc, in the trash. I click on empty trash only to discover a couple of things are still there. A second 'empty trash' always solves the problem. It's not everytime I empty, perhaps 2 out of 5, but when it happens, I see two 'empty trash' dialogues flash onto the screen, one underneath the other. Any ideas?

Everytime? Surely that can't be the answer, merely a workaround?
In any case, isn't this method designed to delete all files including those that are locked.
My problem is that the files I find remaining are not of the locked kind, and while this method may work, I shouldn't have to use it under normal conditions.

I'm considering buying CC but need to know does it allow me to store photos taken while on location via a laptop and then once I am back home retrieve them in my pc through CC, thus enabling me to keep memory cards empty at the end of each day shooting?

This would be the main reason for purchasing CC but I can't seem to find the info to answer my question if anyone can help?

You can place photos in the Creative Cloud Files folder on your computer and they will be synced up to the file storage. You can try a free trial with 2 GB of file storage to see if the system works for you before purchasing.

Spreadsheet cell format.

How can I enter numbers with leading zeros? Format submenu gives me Number format only. Should there not be a general cell format with an option to insert text?

"This is very helpful. I have a spreadsheet with about 3500-4500 numbers in Column A (ISBNs) that I will have to restore to 10 digit numbers"
Hi Bilynbrook,
Welcome to the discussions and the AppleWorks forum.
Since all of your numbers are currently in the first column of your spreadsheet, you'll probably want to have the 'corrected' ISBNs in a column to the left of the rest of your data.
Click on the header to column B to select the entire column, then press shift -command-I to Insert cells. You'll get a new (empty) column B, and all of the data in the spreadsheet (except the contents of colunn A) will be shifted one column to the right.
If column B is no longer selected, reselect the whole column by clicking its header again. Type one of the formulas below, but don't press enter or return. Instead, press command-D to fill the formula into all the cells Down the column. Then, if you have column title information in the first row (oro more), replace the formula in the title row(s) with the appropriate title information.
Formulas:
1. Use this version if ALL of the ISBNs have already been entered, Delete the formula from any rows below the last row containing data.
2. Use this formula if you will be entering more ISBNs later. Leave the formula in the rows which contain no data as yet—the extra part keeps these cells empty until an ISBN (or other data) is entered into the cell in column A.
=IF(LEN(A1)>0,=RIGHT("0000000000"&A1,10),"")
Once you've entered the formula and filled it down the column (and done the editing mentioned above), it's a good idea to Lock all the cells in that column to prevent accidental changes. You'll still use column A to enter the ISBNs, but you won't want to see it on the page. The easiest way to hide the column A is to select it by clicking on its header, then go Format > Column Width, and set the width to zero. To enter a new number, click on column B in the appropriate row, press the left arrow key once to move to column A, then enter the number.

How to implement If and then logic in Numbers?

Having looked in the formulas section of both teh Help and User guides I can see that it is possible to compare using the IF function...and that produces a True or False output...but any further than that and I am lost. i can't seem to find the 'THEN' function....or a Copy function
I have a series of columns exported from a Pilot Logbook program in csv format
One column (A) is the pilots operating capacity (P1, P2, P1/us) another column (B) is total flight time
I need to create three new columns C,D,E (P1 P2 and P1/us)
I can see that in each cell of the new columns I need a formula which in words would read something like
IF contents of cell A1 = "P1" THEN copy/duplicate the value of B1 to C1
IF contents of cell A1 = "P2" THEN copy/duplicate the value of B1 to D1
IF contents of cell A1 = "P1/us" THEN copy/duplicate the value of B1 to E1
I have spent two days on this already, and all I keep getting is the little red triangle saying the formula contains a syntax error.
Am I perhaps attacking this problem in the wrong way...is there an easier way to do this?
Thanks
Neil

Hi Neil,
Further to Yvan's post, here's some general information regarding formulas and the IF function in particular.
Formulas always return a result to the cell in which they're entered. They can 'pull' information from other cells, but they cannot 'push' data into other cells. For example, a formula in cell C2 can fetch (and use) data from cell B2, but can place its result only into cell C2, the cell in which the formula has been entered.
The syntax for the IF function, as shown in the iWork Formulas and Functions User Guide is:
=IF(if-expression,if-true,if-false)
Another description would be: IF(THIS is true,THEN do this,ELSE do this)
if-expression is an expression that may be either TRUE or FALSE. An example from your case is:
A1="P1" ('the contents of cell A1 is the text "P1"
if-true is the instruction to follow when the if-expression is TRUE. (aka the THEN part)
In your first case, this is expressed using the cell reference 'A1', which means 'return the value stored in cell A1'
if-false is the instruction to follow when the if-expression is FALSE. (aka the ELSE part)
In your first case, this is expressed using the empty string ( "" ), which means 'return the text enclosed by the quotation marks' (which for "" is a text string of zero length, known as the empty string or a null string—as close as we can get, using a formula, to keeping the cell empty.
And a suggestion regarding using the Formulas and Functions User Guide:
Every function described in the guide comes with at least one example. If you're having trouble with a function, open a NEW blank spreadsheet, go to the guide and try one or more of the examples.
Unfortunately, both example for IF use text strings in the if-true and if-false parts.
Here's the first:
=IF(A5>=0, “Nonnegative”, “Negative”)
Try this version for an example closer to what you want:
Enter "Nonnegative" into C2 and "Negative" into D2 (leave off the quotation marks).
Enter this version of the formula into B5:
=IF(A5>=0,C2,D2)
Enter this revised version in B6
=IF(A5<0,D2,C2)
Try entering some numbers into A5. Both formulas fetch the data from the same cells and will show the same result for any number entered in A5.
Regards,
Barry

Empty cell until value entered in different cell

I am trying to create a formula that will leave a certain cell empty until the first cell is populated. The problem is that the cell that first needs to be populated will not have the same value in it.
Basically, I am creating a daily chart where I will have to populate numbers in column A, which will then populate all the other columns. Until the cells in column A are populated I want all the other cells empty. The cells in column A will be populated
with different numbers every day, which is my problem.
Additionally, if the cell is then populated, the other cells will have to do calculations. It should be something like "Once the cell in column A is populated with a number, column B will have to calculate A1-C1. Until that point column B will have
to stay empty.
I'd be grateful for any help.

Enter the following formula in B1:
=IF(A1="","",A1-C1)
This formula can be filled down.

Empty Cells in Report

Hi Experts,
After executing the query, I am getting some cells which are empty without any zero / any value....
Is there any setting to display those cells with zeros ........
Thanks in Advance..
Regards,
Nagamani

Hi Nagmani,
After calculation if ur getting few of ur cells empty even the desired is 0 then in this case u have to create 2 more Calculated key figure and to write something like this in ur Figure:
Suppose the blank ciolumn name is KF1
Then create a KF2 and type below formula:
in KF2 write : KF1 + 1.
Now create another KF3 in that use the below formula:
(KF2 == 1) * 0 + KF1.
KF3 wil be ur final column then,
As the blank space is not zero so directly adding 0 to that will not serve to ur purpose u need to create two more KF as suggested above.
Its a common problem faced as such there is no settings for this so need to do little +, - with Zero so that u can get the 0
Thanks

Mailboxes keep emptying and refreshing

I am having a problem where my mailboxes keep coming up empty and then taking a long time to refresh (giving me the number of "incoming" messages that equals the entire content of my mailboxes). This happens for my icloud-based email (.mac) as well as gmail. Any ideas as to how to prevent? I am running the latest OS on a Macbook.

Still having mail problems. It seems to me that the Preferences, where I un/check the boxes for saving stuff on my server, is working backwards. If I uncheck them, I end up with more mailboxes, either under a folder called "IMAP Account" or in their own folders which have IMAP account in parenthesis afterwards. I try to delete these or use the "use this folder for..." option yet these extra folders/mailboxes keep coming back.

Can i automatically put a value in a cell based on the text in the previous cell. Cell D is a pop-up menu of five products i use. Each product has a different numeric value which will appear in cell e based on which product is chosen in cell d

I would like product cost to automatcally be entered Based on what product is selected from pop-up menu in product column
Feild
Feild Operation
Date
Product
Product Cost

Hi Neil,
This is usually done with one of the Lookup functions, such as VLOOKUP:
The basic formula is: =VLOOKUP(D,'Table 1-1' :: $A:$B,2,FALSE)
To keep the cells in the bottom five rows 'empty' until an entry is made in column D, the basic formula is placed in an IF statement: =IF(LEN(D)>0,VLOOKUP(D,'Table 1-1' :: $A:$B,2,FALSE),"")
And to catch errors in data entry (such as the one in row 5), that formula is enclosed in an IFERROR statement:
E2: =IFERROR(IF(LEN(D)>0,VLOOKUP(D,Price list :: $A:$B,2,FALSE),""),"Not found")
The last is the formula used in the table above. Enter in E2, then Fill down the rest of the column.

Whenever I try to open iPhoto, a message comes up saying that 148 photos have been found in the iPhoto Library that have not been imported. It asks me if I want to import them and I say NO but then it places them in a recovered photo folder. I keep deleting the empty recovered photo files but it just keeps asking me every time I go to open iPhoto! I'd love to just get rid of the "found" photos (I can't open them anyway!)
How do I get rid of them so that I can just open iPhoto straight up without this?
Linda

Open your iPhoto Library package with the Finder.
Click to view full size
look for a folder titled Import or Importing and move it to the Desktop. Launch iPhoto to see if the message goes away. If there is no message check the contents of the Import folder to see if you want to keep any of those image files (usually they have not been imported into iPhoto). If you want to keep them then drag the folder into the open iPhoto window to import.
