I am trying to retain a value when I bring up a client in a form. If the client owes money it should show up immediately before entering in another payment. This way if the client does not make a full payment or an overpayment I can adjust it to the amount owed field. The problem I am having is that the field is not retaining the value. I get a payment difference value and set it to the amount owed but it won't hold the value. When I bring up the same client again the amount owed is blank. How do I hold it? Do I use a lookup function? Any recommedations would be appreciated.
