Need help with a spreadsheet

Im trying to do a spreadsheet to help out one of my friends.

He started doing it on his Windows 7 comp, then emailed it to me on my Ubuntu laptop which has Libra Office.

Well everything was fine when I picked up on my laptop. Then I did a few pages, saved it, and sent it back to him. Now when I try to do some more, leading zeros disappear. I have to type a bunch of numbers like 09 and 05 and the 0 always disappears.

It does this on BOTH computers now. So WTF happened?

Put a leading ' or reset number format you troglodyte

I got that problem fixed. But then I started getting shit spilling over to the next cell when I was typing longer ones. I just started adding shit on Google Docs and everything seems to be working fine now.
