Hi Paul,
This.destroy instead of thisform.de.closetables would correct the problem I see. But I couldn't get yet why only return .f. there is not sufficient. With default DE values tables would close. Anyway I want to point out something else, as I could see you don't need something from form up to that return .f. so why not do it in a prg or form (whereever do form called) and don't call it (instead of return .f.). And I would change the scan..endscan code to :

scan
  insert into cpayment ;
     (cpay_pk, cpay_schdate, cpay_lessdate, cpay_paydate, ;
      cpay_flag, cpay_paid, cpay_instamt, cpay_update, cpay_updInstBal) ;
    values ;
     (payment.pay_pk, payment.pay_schdate, payment.pay_lessdate, ;
      payment.pay_paydate, .f., payment.pay_amt, payment.pay_instamt, ;
      "", .f.)
endscan
