put your open code in a standard module called Auto_Open. it will only run when
the workbook is opened manually not via code.

if you have your code in a workbook_open module, it will fire whether the
workbook is opened manually or via code.

I have a workbook that runs a macro when it open. I have a second workbook
that needs to open the first workbook and import data. How do I prevent the
opening macro from running when the other workbook opens it?

Using Excel 2003

Thanks in advance!
