Dynamic selection of check boxes on selecting a check box

Question

Hi Friends,
I have to select the check boxes which are herarchically lower to a top check box,dynamically.
Eg:
Checkbox1
   checkbox2
   checkbox3
so if i select check box 1, on the screen both checkbox2 and checkbox3 have to be selected.
I did like below.
AT SELECTION-SCREEN OUTPUT.
  LOOP AT SCREEN.
    IF P_ALL = 'X'.
      P_VAT = 'X'.
      P_NAME = 'X'.
    ENDIF.
    MODIFY SCREEN.
  ENDLOOP.
but values are checked but on screen its not checked.
how to handle this.
Regards,
Simha
