I have a file "File01.xls" with a range "List". This file has a UserForm1
with a ComboBox where the RowSource is range "List". The UserForm is
accessible from any open file. How do I set the RowSource to the "List"
range so it works regardless of the current active workbook. I get an error
when the current active file is not "File01.xls".

Thank you,

Steven
