Hi guys, I am currently have this script on frame 5, AS3:

\*var timer:Timer = new Timer (2000,45);  
timer.addEventListener(TimerEvent.TIMER, timerFunction);  
timer.start();

function timerFunction(event:TimerEvent):void  
{  
var mcClip:Cloud = new Cloud();  
mcClip.x = 400;  
mcClip.y = yVar;  
addChild(mcClip);  
var yVar:Number = (Math.ceil(Math.random()));

back\_btn.addEventListener(MouseEvent.CLICK, backMain)  
function backMain(Evt:Event):void  
{  
gotoAndPlay(1);

}\*

Everytime when I hit the BACK button which bring me to frame 1, the “timerFunction” still looping.

My question is, Is that a way to kill this script when I go back to frame 1?

Help will be much appreciated.  
Thanks.
