I have a combo box that selects records to add to a subform (the many side of a join table). I have criteria in its row source query that limits possible selections to those from another table that are linked to the ID of the current record in the main form ( the 1 sides of the join)and have a certain field value "Quoting" The user selects an item from the list , presses a button and it adds the record to the subform. I would like that record not to show up in the combo box any more. How can I do that?
