I have code in a workbook_SheetCalculate event that changes an edit box in a
custom toolbar. The toolbar doesn't exist until a user pushes a button on
the worksheet, and after using the toolbar, the toolbar deletes itself when
the user is done. Thus, the code activated on SheetCalculate produces an
error when the toolbar doesn't exist. How do I write code to check for the
existence of the toolbar?

Thanks
Dave
