I am running a module in Access that exports data to Excel. When I ran this
DB on Windows 2000, I had no errors.

After switching to Windows XP, I get an error that debugs to the VBA code in
Access.

Once the macros is running, the Excel spread sheet opens. If I click on
another tab in the worksheet I get this error in my Acess VBA:

Run-time error '50290':
Application-defined or object-defined error

I am not sure where this problem stems from: Access, Excel, VBA or Windows
XP.

Any advice would be greatly appreciated!

Thanks in Advance,
Elena
