It appears Excel 2003 and Excel 2007 put the user forms in a separate module
from the modules that excute code in the workbook.
In Excel 2003 I had code that referenced the form via UserForm.show in the
main startup module . This code generates an error in Excel 2007. Also
calls to subroutines in the code behind the form from the other modules
generates and undefined error. How does Excel 2007 link these two modules
now so that one can reference items in them.

Thanks
