ActionScript 3.0 :: Timer On / Off Refreshing Picture X Status

I am creating flash panorama image viewer. There is a movie, left, right button, and some other buttons. Left and right buttons are triggering Timer, on MouseDown (timer is on), on MouseUp, switches timer off. timer function moves picture
picture.x = picture.x + 20 (other side -20).

That works well. Other buttons are moving picture to the specific locations of picture.x and that works well too. There is a dynamic text, which is reading value of the picture.x Dynamic text is reading well, if left and right buttons are clicked, but can not read if other buttons are pressed, ones who are taking picture to the specific location. I presume that it is not picking up the value of the picture, because the program was not refreshed after taking picture to the new location. How can I refresh program in order for dynamic text to read value of picture.x? I am using timer stopping in order to prevent memory leakage. I use AS3.

There is some actual code illustrating what I am talking about:
//timer created and stopped
var timer:Timer = new Timer(33);
timer.addEventListener(TimerEvent.TIMER, movingCode);
timer.stop();
function movingCode(event:Event):void {
