I have an Excel workbook that was put togethering using Excel 2003 on
Windows XP. I used the Visual Basic Editor to input the code and
everything worked fine.

Now that I open this file using Excel 2007 on Windows Vista nothing
works. I have added the workbook to a trusted area. When I run the
code I get a "Run-time error '50290'" for every line.

What went wrong? How do I fix it?

Thanks!
