Hello Experts,

I am trying to compile my database application, but I seem to be running
into an error on one of my forms in the BeforeUpdate event.  Here is the code
for my validation:

Private Sub Customer_BeforeUpdate(Cancel As Integer)
If (Customer.Value & vbNullString = vbNullString) Then
  MsgBox "Customer is required!", vbOKOnly
 
 Cancel = True
 
 Customer.Undo
Else
End If
End Sub

When I compile it highlights the Customer.Undo line and says Method or data
member not found.  Kind of odd since I am using the same statement on another
form which does not produce the error.  Any suggestions would be greatly
appreciated.

Thanks!
