I get the above stated compile error when I run the following code:

Dim myfile as String
myfile = "Book1.xlsm"

If Module1.IsWbOpen (myfile) Then
' Do stuff
End If

------------------[ IsWbOpen() is in Module1]--------------------

Public Function IsWbOpen(WbName As String) As Boolean
For Each wb In Application.Workbooks
If wb.Name = WbName Then
IsWbOpen = True
Exit For
End If
Next
End Function
--------------------------------------------------------------------


Does anybody know what the heck is wrong here??? I know i am
definitely passing a String variable into "IsWbOpen()", yet I am
seeing a compile error.

Thank you!
