Please help.

If a have a file written in XP that I saved to 97-2002 & 5.0/95, should all users running excel 95 or higher be able to open it? What is the best way to save a file to earlier versions to allow the most possible of users to open. Some users that I have sent the file to are unable to open it. Any suggestions to resolve the issue?

Thanks much.

Skiman.
