I want buttons on worksheets in my workbook to run a macro that is
stored in an add-in

I have called the macro 'Public Sub xxx()'

I have created a reference to the add-in in the workbook that will
have the buttons.

But I can't 'see' the macros in the add-in to be able to assign them
to the buttons.

Can I do it?

how?

Cheers

Michael
