[AccessD] Adding an Excel Button and Associated Macro from Access

I am trying to create a new Excel Workbook from Access.  The Worksheet
in this Workbook needs to have a button with an associated Macro.

So far I have been able to create the new Workbook and Worksheet and add
the button to the Worksheet.  This works nicely.

However, I can't figure out how to add the Excel Macro from Access.

Is this possible?

If so, an example would be most appreciated.

Thanks,

Brad
