Referencing a cell that was set to null

I have a spreadsheet which I designed in Numbers from iWork 8. I recently upgraded to iWork 9.
I have cells that were set to null ("") with an if statement, and then reference them in later formulas. In iWork 8 everything works fine, but in iWork 9 I get errors saying...
'The operator "+" expects a number, date, or duration but found "."'
I can't find any way around this, any help?

Larry,
It's difficult to make a specific recommendation without knowing more about your table. A general workaround would be to use SUM() since SUM is tolerant of the inclusion of strings, blanks, etc.

After refreshing ALV display, set it to the current cell that was modified.

Hello Experts,
I am currently using cl_gui_alv_grid for my ALV grid display. I have 1 editable column
which lets users input values. Now, When users press 'ENTER' in the keyboard I refresh
the ALV display to reflect the changes done. But the display always "moves back" to the first column
so it is tiresome to find the current cell that was modified. My question is, how do I set the ALV
display to just "stay put" in the current cell that was modified after pressing 'ENTER'?
Hope you can help me guys.Thank you and take care!

I have an iPhone that was set up as a backup of another phone. I want to sync it with my current library; am afraid of losing synced contacts. Will I? Can I prevent this?

The older phone in question was a work phone that was set up by the owner and then distributed to employees for use. I have a new phone that will be for personal use that I have backed up from the work phone;mainly for the contacts. I want to sync the new phone with my personal library, and I go to do so and get the infamous "erase and sync" message. Will this erase they synced contacts if I do this? (Contacts are what are most important in this case; there is no music stored, for the backup had no music.) If it does, can I prevent this from happening without having to manually replace the contacts?

You did not restore the new iPhone.
The first time a new iPhone is connected to iTunes on a computer that is used to sync with another iPhone or iOS device or that was used to backup another iPhone or iOS devide, you are prompted to transfer the backup for the other iPhone or iOS device, or set up the new iPhone as a new iPhone.
Since the old iPhone was synced with iTunes on a different computer, all iTunes content on the new iPhone (which is none at the present time) will be erased first.
The warning message should indicate all iTunes content will be erased from the iPhone, which is iTunes content only.
If you are syncing contacts with a supported address book app on this computer and the supported address book app on this computer includes any contacts, you will be provided a merge prompt for the contacts, which you want to select. Otherwise the contacts on the iPhone will be replaced with the contacts in the address book app on the computer with the first sync.

I have an ipod touch that was set up on this computer. It is a mac. It hasn't had an update in a while and it needs an update to update apps and download new apps. It will not show up in itunes to get the update, nor will it let me update on the iPod. ???

I have an ipod touch that was set up on this computer. There are other ipods hooked up on this one, but this one won't work. it hasn't had an update in a while, and it won't let me update it because it won't connect to itunes, or show up on the computer. There is no place that says there is a software update on the ipod. I was wondering how to get it updated or at least get it connected to itunes?

HT1226 how to add security key to airport extreme that was set up without? a key?

How can I add a security to my airport extreme that was set up without one?

Will have to have re-set up my airport express or will the extreme just work with the express? I have the express locked down and I thought about unlocking the express? What would I do to set this up? Any help I would greatly appreciate it!!!
You should set up the Extreme as your main router and eventually the Express to stream music or to extend the wireless.
After the Extreme is set up and running, just set the Express e.g. to "Join a wireless network".
Alternatively reset the Express to factory default (see manual) and configure it from the scratch to your needs.

I cant access any of the content that was in my music library that was set up on my old destroyed laptop. so Home Share cant be used. Is there a way to pull all of the music content, not just iTune purchased music from my 4th Gen Nano back into iTuunes?

I cant access any of the content that was in my music library that was set up on my old destroyed laptop. so Home Share cant be used. Is there a way to pull all of the music content, not just iTune purchased music, from my 4th Gen Nano back into my new iTunes set up on my new home compter?

It has always been very basic to always maintain a backup copy of your computer.
Use your backup copy to put everything back.
The music sync is one - way - computer to ipod. The only exception is itunes purchases.

The URL that was set for my homepage redirects to a network authorization page even though I cannot connect to that network.

I am no longer within range of a network that I was ''attempting'' to connect to as ''guest'' and now the guest registration page for the network overrides the url that was set for my home page in Firefox. (I never actually established a connection to the internet on that network because the guest username and password repeatedly failed.) The redirect executes whenever I type the URL, www.yahoo.com, into the address bar or when I follow a link from a search engine to that URL, or when I click the home button. How can I stop the
redirect? I deleted all network locations that contained that network and cookies that contained the network name but that did not stop the page redirection. I do not believe this to be a virus or malicious network because it was at an research institute. I looked in prefs.js for any keywords from that network but I did not find anything obvious.
Thank you for your help.

Easily fixed: clear the cache.

I have an old iCloud account on my phone.
This account was set up using an old Apple ID and password.
Since then I've changed both id and password.
In order to delete the existing (old) iCloud account from my phone I need to provide the old password from the old and defunct account.
I don't remember that password.
I've tried resetting it through the support network but to no avail.
I need to delete the old account in order to set up a new one.
Any thoughts?

If the ID is yours but you don't know the password, you'll have to reset it (http://support.apple.com/kb/HT5787). If the ID belongs to a previous ownder of the phone, you'll have to either get the ID and password from them, or have them erase the phone and remove it from their account as explained here: http://support.apple.com/kb/TS4515.

HT1212 I took the passcode lock off of my iPhone 5 and now I can't get on to my iPad. It is asking for the passcode and when I use the one that was set up it locks me out. How can I get past this?

I have the iPhone 5 and with the new sofware update it added a passcode lock. Same for the iPad. I removed the passcode lock from my iPhone and now I can access my iPad. It is still asking for the four digit passcode. I tried using the one that was orgingally programed and it disables it every time. How can I get past this? I have tried to do a restore and it still takes me back to the lock screen. Please help!

Force iPad into Recovery Mode. Follow step 1 to 6 very closely.

I would like to get rid of the MSN homepage that was set a a default home page when I use firefox. I want to go back to the regular firefox homepage. How do I do this?

I want to get rid of the homepage that I set a while ago that goes directly to MSN news and just go back to the regular firefox search page as a default.

It's helpful to give more specific feedback if you can.
Here's the process to roll back:
First, I recommend backing up your Firefox settings in case something goes wrong. See [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information] (copy your whole profile folder).
Next, download and save Firefox 3.6 to your desktop for future installation. http://www.mozilla.com/firefox/all-older
Close Firefox 4, and uninstall it. Do not remove your personal data and settings, just the program.
Then finally you can reinstall Firefox 3.6. Unless you have installed an incompatible add-on, it should pick up where you left off. If there are serious issues, please post back with details.
Note: I haven't actually tried this myself!

HT1320 Can i sync a different itunes account to an old Ipod that was set up with a different account that is no longer active

I have found my old ipod that I would like to sync to a different itunes account that it was not set up, how do i sync it to my current account. The old account information is lost and do not have it

If you used automatic syncing, an iPod syncs with an iTunes library, not to an account, such as your iTunes Store account (Apple ID). So, if you still have the same iTunes library, it should still work with that library, even if you no longer have access to an "account."
However, it can only sync with one iTunes library at a time. If it is currently set up to sync to an iTunes library that you no longer, you can set it up to sync to your current iTunes library. But when you do that, the iPod's existing content is replaced by content from that iTunes library.
If that iPod was previously set up using the Manually manage music setting (you dragged songs to it in iTunes to load it), instead of automatic syncing, it is NOT syncing to a particular iTunes library. In that case, you can add new items to it from your current iTunes library. But you cannot set up automatic syncing without replacing its existing content.
You can post back to clarify your situation, and what you ideally want to do.

How to sync an iPad that was set up at Apple Store?

My wife bought our iPad2 and had the Apple staff set it up for her at the Apple Store.
Since then, we have downloaded many apps directly on the iPad without connecting to iTunes.
When I tried to download some new apps, the iPad says it requires iOS5.
But when I tried to download iOS5 via our iTunes, it says I must connect my iPad to the computer that I sync'ed with originally.
The trouble is that the iPad has never been sync'ed with our iTunes before.
My questions are:
Do I need to take it back to the Apple Store to get it updated?
There is no way to find out which computer the Apple Store staff used to set up our iPad.
So even the Apple staff would need to do the update via a different computer.
If I do a sync and upgrade like that, will I lose everything currently on the iPad?
How can I make sure everything is backed up before my upgrade?
If my iPad is not paired up with my iTunes, how do I do the backup?
I thought about using iCloud, but I don't want to pay for the service beyond the initial free allocation.
I heard that for iOS5 devices, first 5GB is free on iCloud.
But I don't think 5GB is enough to back up the data from my 64GB iPad.
So I guess I must make my iPad work with my iTunes.
Any suggestions and clarification would be greatly appreciated.
Thanks in advance.

Okay! I have completed all the step your outlined and I have verified that the App Sync'ed and the iPad backed up. However, when I opened my Books library on my iTunes, the free pdf files that I have downloaded on the iPad are not sync'ed to the iTunes. When I checked Sync Books under the Books tab of my iPad, it prompts "Are you sure you want to sync books? All existing songs, movies and TV shows on the iPad "My iPad" will be removed." Obvious, the sync tries to match the empty content of my iTunes library with the iPad. I believe if I click "Sync", all my book contents on my iPad will be all gone. These .pdf files were free downloads and they were not purchased from iTune Store. So how to I back them up or move them into the iTune library? Can I mount the iPad as an external disk and copy these files over? Where will they be stored on the iPad. I click on "Books" listed under My iPad, it has an export command. I exported it and it seems to only output a text file containing only the list of books and not the contents of these books.
I was able to copy the photos I took on the iPad to the iPhoto on my computer. But it is an iPhoto import function, not a iTune function. Can I do something similar to the Books on my iPad?
Now I have an iTunes that is paired with my iPad, but the iPad's media contents are not on the iTunes.
i.e. if I sync'ed everything all my media contents may be wiped clean.
Besides, my initial goal is to upgrade my iPad to iOS5 without losing its existing contents. Whenever my iPad is connected to the iTunes, a message pops up that says "A new iPad software version (5.1.1) is available for the iPad "My iPad". Would you like to download it and update your iPad now?" When I click on the "Download and Update" button, another warning pops up that says "Updating to iOS 5.1.1 will delete all of the media, including iTunes Store purchases, on your iPad. To perserve your content, apply this update on the computer where you sync music, videos, and photos."
I dare not click the "Update" button because all of my iPad contents are not in my iTune library. So the contents may be inside the Backup that I did in step 4 of your instructions. But I am taking a big risk, because it is is not, then I'll lose all my media contents.
I need to know:
Is there a way to transfer media contents, e.g. downloaded free pdf files (books) to my computer before I upgrade my iOS from 4 to 5?
