You can create your Excel form in Excel 97 or later. The incompatibility between Excel 95 and 97 workbook files caused major frustration for a lot of Excel users. Since Excel 97, all workbooks are transparently compatible. Newer features not supported by older versions are now ignored without error.
There is still an incompatibilty with the ActiveX interface between Excel 97/2000 and XP/03. You will need two different compilations of your program to work with all versions. Michael Munroe Certified LabVIEW Developer www.abcdefirm.com
