-----Original Message-----
I am relatively new to VBA in Excel and am having
trouble.
I am trying to call a macro in another workbook and pass
a
parameter to that macro. Help does not provide a
reasonable explanation or Example to follow. I would
appreciate any help I can get in solving this problem!

TIA
