I have a routine in my one Userform....

Private Sub UserForm_Activate()
Call Macro 1
End Sub

I also have the following in my module code

Set MenuItem = ....
With MenuItem
..Caption = "Validate"
..OnAction = "UserForm_Activate"
End With

When I try to run the menuitem, I get

The macro 'filename.xls!Userform_Activate' cannot be found.
Any thoughts?
