How to keep loop stopped in the gui

Hey, so my problem is my function stops when i press the stop button on the gui, but it doesn't stay stopped. It will continue on to the next value in the for loop. The following code is how i'm trying to stop the function:

for i = 1:length(DRAW)
            drawnow()
            stop_state = get(handles.STOP,'Value');

              if stop_state
                  kill = 1
              else
                  kill = 0
              end

              [out_Params, Inter_params, out_J, time, FLAG] = RECIRC_FO_design_GUI(sol_props, ...
                  INLET_PARAMS, FEED_PARAMS, DRAW_PARAMS, SYSTEM_PARAMS, MEM_PARAMS, MW_salt, DRAW(i), kill);

              if kill
                  kill = 1;
                  break;
              end

          end
I put a condition in the function itself that would stop it, but when i check the value after hitting the stop button, the value is still 0 instead of 1. I've looked at the previously answered question regarding this topic, and they work just the function won't stay stopped. the stop button is just a push button that when pressed sets it's handle value to 1.

Yeah, doing it by a button doesn't work. The problem is that your copy of handles is not getting updated. What I do is to have a checkbox that says "Finish now". I make it visible when the loop starts, and when my loop gets to the bottom, it checks the value of the checkbox, and if it's true, it sets the checkbox to false, sets it invisible again, and breaks out of the loop.

That did it. Thank you
