I do volunteer work with an out-of-state non-profit organization that runs
Office 2000. I wrote several VBA programs for them using Excel 2002. I
sometimes get nailed on revisions that I send because of my newer version.
Almost always the problem is that I included system defined variables
(usually generated when I record a macro) that were not used in the prior
version.

Can anyone offer an easy way for me to check the code for back compatabiity
before I send it to them.

Thanks for any suggestions.
