I've followed 2 books exactly, as far as I can tell, but "it" doesn't work.

I have in a Standard Module [modBusinessLogic]:
_____________________________

' General Error Handler to be called from most procedures

Public Sub GenErrHand(lngErrNumber As Long, strErrDesc As String,
strModuleSource As String, strProcedureSource As String)

 (I'd put the code in here, but this Sub isn't even being "called" - that's
the problem)
       
End Sub
_________________________

I have in a Form's Module [Form_FA1_OrgMaster_All]:
_________________________
 Private Sub cboOrgs_AfterUpdate()

   On Error GoTo HandleError

' Populates a combo box on the Financial Reports subform with reports titles
for the Org just chosen

        (((NOTE: the first subform name below is purposefully misspelled -
not supposed to be ...FinRpt..., but rather ...FinRpts... - this sets up an
error to test Error Handler)))

   Me.subfrmctrlFinRpt!cboIS_BySrv_List = Null
   Me.subfrmctrlFinRpts!cboIS_BySrv_List.Requery

                           ... More Code ...

   Exit Sub
   
HandleError:
   Dim strPrcdrName As String
   strPrcdrName = "cboOrgs_AfterUpdate"
   Dim strModName As String
   strModName = Application.CurrentObjectName
   
   GenErrHand Err.Number, Err.Description, strModName, strPrcdrName
   
   Exit Sub

 End Sub
_________________________
When I tested (with the Immediate Window) the Error Handler with a procedure
in the Standard Module that would create an error, it produced the Message
Box I want.

But when I test it with the set up above (chosing an Organization in the
Combo Box on the form), instead of getting the Message Box I want, I get
"Compile Error: Method or data member not found" - which is obviously the
regular VBA Message Box.

Why isn't my Error Handler being "called" correctly? Thanks
