We are using Excel Macros pretty extensively.

Workbook is created in Excel 2003. Macros are written and run.

When the same workbook isopened in Excel 2002, the macro halts with the
error message

Can't Compile
Can't Find Project or Library

The library for Excel 2003 is

It fails though on some pretty low level commands that ARE in referenced
libraries.
Format$, LCase, UCase - stuff like that.

The library for these commands is the Visual Basic for Applications Library.
This is correctly referenced in the References window of both versions. When
I use the object browser in both revisions, it correctly finds the function,
but it will not compile.

We'd like to be able to pass these workbooks back and forth. We're not using
any features that aren't supported in both versions. Any thoughts on how to
make this work?

Thanks,
Tony
