Push button in a table

Question

Hi,
I have an internal table and showing this itab with dialog programing. I have inserted a new column in table, I need that when client has pressed such as 5th line I want to get 5th line's information. I have created a field which's length is one character and gived this field's name as 'see' in itab and I gave the button name as itab-see. But, when user pressed any line I see that the itab-see field has not changed such as a radio button or checkbox. How can I get which line's button has pressed and that line's table information.
Thanks.

if you are using a table-control you can use a pai module like this:
MODULE PICK_UP.
establish which line was selected on the first time through
  IF SY-STEPL EQ 1.
    GET CURSOR LINE w_selected_line.
    IF W_selected_line = 0.
      W_selected_line = 1.
    ENDIF.
convert the relative line to the actual line number in the table by referring to the table-control
    w_absolute_line = w_selected_line + tc_???-top_line - 1.
  ENDIF.
In your screen's flow logic you need something like this in the PAI section:
  LOOP AT your_table.
  MODULE pickup.
  ENDLOOP.
However, If you are using a steploop I'm not sure how you do it and am interested in the answer myself!
