I'm in the process of creating a form with lookup fields.  The problem
I'm having is this:  When you enter data into one of the look up
fields, the data says there.  I need it to clear the field after you
hit Enter or Tab.  How do I do this??  This is what is displayed 'after
update':

Private Sub Combo11_AfterUpdate()
   ' Find the record that matches the control.
   Dim rs As Object

   Set rs = Me.Recordset.Clone
   rs.FindFirst "[InvoiceNumber] = " & Str(Me![Combo11])
   Me.Bookmark = rs.Bookmark
End Sub

What's missing?
