Hi rick
You can work with files in the 97-2003 format or in one of the new 2007 formats.
If possible keep 2003 on your system so you can work/test in both versions

I want to install Excel 2007, but I create and share spreadsheets with users
who will be using Excel 2003. Are there any compatability issues that I
should know about?
