Auto Run Macro

[Dorci]

Excel 2003 - I have this macro, but it doesn't run when I open the workbook:

Private Sub Workbook_Open()
Application.CommandBars("Cool Macros").Visible = True
End Sub

I can run the macro manually AFTER opening the workbook, but I want it to
run automatically. My ultimate goal is to install the "Cool Macros" toolbar
for ANYONE who opens this workbook. Any idea what I'm doing wrong.

Thanks in advance.
