I have an Excel add-in that makes use of a userform
that uses a spreadsheet object. When upgrading my
computer to Excel 2003, my application did not
recognize the spreadsheet object. Therefore, I
recreated the spreadsheet object and set the
references for the VBA project to the current
Microsoft object library. The application now works
again in Excel 2003. However, when I try to use this
add-in with my work computer which uses Excel 2002, I
get an error that this spreadsheet object is not
recognized.

Are there any work arounds that I can use to help my
add-in work across these versions of Excel?

Many thanks for any advice.
