I have problem opening an Excel file. It comes up with "Visual Basic" error
window, and the error message is "Module not found".

I'm using Excel 2000 on Windows 98.

Help provides following info. about the error -
------------------------------------------------
Module not found

Modules aren't loaded from a code reference €” they
must be part of the project. This error has the
following cause and solution:

The requested module doesn't exist in the specified
project. For example, the statement MyModule.SomeVar =
5 generates this error when MyModule isn't visible in
the project MyProject.
See your host application documentation for
information on including the module in the project.
------------------------------------------------

Excel file is provided by a friend who uses Mac, and I think it contains
some macros.

Any idea? Thanks in advance.
