How to hide parameters AUTOMATICLY based on radio buttons being pressed

Question

I have multiple radio buttons and with each radio button I have parameters that appear on screen for user to enter data.   Is there a way to make the selection blocks appear and disappear automatily based on the user  pressing the radio button?
My current coed works only if I press the enter key but not automatily when the radio button is pressed.

hi, have a look this example, it works as u want.
SELECTION-SCREEN BEGIN OF BLOCK blk2 WITH FRAME TITLE text-002.
PARAMETERS: r_ps TYPE c RADIOBUTTON GROUP rd DEFAULT 'X' USER-COMMAND abcd, "radio button server
               r_as TYPE c RADIOBUTTON GROUP rd . "radio button for application server
SELECTION-SCREEN END OF BLOCK blk2.
SELECTION-SCREEN BEGIN OF BLOCK blk1 WITH FRAME TITLE text-001.
PARAMETERS: p_pfile TYPE rlgrap-filename MODIF ID ccc, "presentation server input file
                p_afile TYPE rlgrap-filename MODIF ID aaa. "application server input file
SELECTION-SCREEN END OF BLOCK blk1.
AT SELECTION-SCREEN OUTPUT.
  IF r_ps = 'X' .
    LOOP AT SCREEN.
      CASE screen-group1.
        WHEN 'CCC'.
          screen-input = 1.
          screen-invisible = 0.
          MODIFY SCREEN.
      WHEN 'AAA'.
          screen-input = 0.
          screen-invisible = 1.
          MODIFY SCREEN.
      ENDCASE.
    ENDLOOP.
  ELSE.
    IF r_as = 'X'.
      LOOP AT SCREEN.
      CASE screen-group1.
        WHEN 'CCC'.
          screen-input = 0.
          screen-invisible = 1.
          MODIFY SCREEN.
      WHEN 'AAA'.
          screen-input = 1.
          screen-invisible = 0.
          MODIFY SCREEN.
      ENDCASE.
    ENDLOOP.
