Hi Emily,

'---------------
Is this normal (that you can't step through with variables in the Sub line),
or a weirdness in my Excel (2000 on WinNT)?

As your macro has an argument (intFileID), you need to
call it from another procedure.


To step though your macro, try something like:

'=============
Public Sub Tester()
Call ChangeSource(intFileID:=5) '<<=== CHANGE
End Sub
'<<=============
