I've created a macro Private Sub Workbook_Open(), but it doesn't run when I
open the workbook. I have set the security to allow all macros and made the
folder with the workbook a trusted site. The marco runs fine if I execute it
using the Macro's menu or from VB.

I don't get an error message or any indication at all.

I also tried Sub Auto_Open() with no result there either.

Can anyone give me a clue as to what might be blocking this fuctionality.

Thanks!
