Need to have pop up window in selection screen and capture the user action.

Question

Hello Friends,
                     I have a requirement, that need to show a pop up window after execution, and to get the action from user using a Push button.
I create a selection screen and a sub screen as window.
After user execute from the selection screen, I am popping up this window.
Window contains some input values to be entered and push button to identify the user action.
I try to capture the user action using sy-ucomm, but it does not hold any value when user press the button.
How to overcome this issue.
Here is the definition of the window.
Pop Up Window for getting values
SELECTION-SCREEN BEGIN OF SCREEN 500 AS WINDOW TITLE title .
PARAMETER : p_vdate LIKE t9aa01-validfrom,
            p_dcggt LIKE t9aa01-hkont,
            p_dcgst1 LIKE t9aa01-hkont,
            p_dcgst2 LIKE t9aa01-hkont,
            p_na LIKE t9aa01-hkont.
SELECTION-SCREEN SKIP.
SELECTION-SCREEN BEGIN OF LINE.
SELECTION-SCREEN POSITION 20.
SELECTION-SCREEN PUSHBUTTON 2(10) text-001 USER-COMMAND SVE.
SELECTION-SCREEN END OF LINE.
SELECTION-SCREEN END OF SCREEN 500.
Cheers,
Senthil

Hi,
Try using the below code.
       data : w_var type string.
       CALL FUNCTION 'POPUP_TO_CONFIRM_STEP'
         EXPORTING
          DEFAULTOPTION        = 'Y'
           textline1            = 'test '
         TEXTLINE2            = ' '
           titel                = 'check'
         START_COLUMN         = 25
         START_ROW            = 6
         CANCEL_DISPLAY       = 'X'
        IMPORTING
          ANSWER               = w_var.
                 if w_var = 'J'.
                 else.
                 endif.
Comments : J indicates Yes and N indicates No
