how to fix error 1009 in flash as3

Question

hi i have been trying to fix this by searching the net for hours and have had no luck so all help is appreciated (it happened when i put the snow in) Thanks in Advance

Here's my code:

Quit.addEventListener(MouseEvent.CLICK, func22);

function func22(event:MouseEvent):void
{
    gotoAndStop(2);
    myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener3);
    myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener4);
}

Help.addEventListener(MouseEvent.CLICK, func33);

function func33(event:MouseEvent):void
{
    gotoAndStop(23);
    myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener3);
    myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener4);
}

var myTimer3:Timer = new Timer(2000,0);
myTimer3.addEventListener(TimerEvent.TIMER, timerListener3);
function timerListener3(e:TimerEvent):void {
Hungry_bar.scaleX-=0.05;
if(Hungry_bar.scaleX<=0.05){
        gotoAndStop(12)
        myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener);
        myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener);
    }
}
myTimer3.start();

var myTimer4:Timer = new Timer(3000,0);
myTimer4.addEventListener(TimerEvent.TIMER, timerListener4);
function timerListener4(e:TimerEvent):void {
Fun_bar.scaleX-=0.05;
if(Fun_bar.scaleX<=0.05){
        gotoAndStop(13)
        myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener3);
        myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener4);
    }
}
myTimer4.start();

Feed.addEventListener(MouseEvent.CLICK,feed2)
function feed2(e:MouseEvent){
Hungry_bar.scaleX+=0.05
if(Hungry_bar.scaleX>=1.5){
    gotoAndStop(14)
    myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener3);
    myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener4);
    }
}

Fun.addEventListener(MouseEvent.CLICK,happy2)
function happy2(e:MouseEvent){
    Fun_bar.scaleX+=0.05
    if(Fun_bar.scaleX>=1.5){
    gotoAndStop(15)
    myTimer3.stop(); myTimer3.removeEventListener(TimerEvent.TIMER, timerListener);
    myTimer4.stop(); myTimer4.removeEventListener(TimerEvent.TIMER, timerListener);
    }
}

//snow

var snowflakes:Array = new Array();
var snowflakeProps:Dictionary= new Dictionary(true);
var max_snowsize:Number = .04;
// pixels
var snowflakesCnt:Number = 150;
var oheight:Number;
var owidth:Number;
init();
function init():void {

    owidth = width;
    oheight = height;
    // quantity
    for (var i:int=0; i<snowflakesCnt; i++) {

    var t:MovieClip = new SnowFlake();//
    t.name = "snowflake"+i;

    t.alpha = .2+Math.random()*.6;
    t.x = -(owidth/2)+Math.random()*(1.5*owidth);
    t.y = -(oheight/2)+Math.random()*(1.5*oheight);
    t.scaleX = t.scaleY=.5+Math.random()*(max_snowsize*10);
    var o:Object = new Object();
    o.k = 1+Math.random()*2;
    o.wind = -1.5+Math.random()*(1.4*3);

    snowflakeProps[t] = o;

    addChild(t);
    snowflakes.push(t);
}
addEventListener(Event.ENTER_FRAME, snowFlakeMover);
}
function shakeUp():void{
for (var i:int=0; i<snowflakes.length; i++) {
    var t:MovieClip = snowflakes[i] as MovieClip;
    t.x = -(owidth/2)+Math.random()*(1.5*owidth);
    t.y = -(oheight/2)+Math.random()*(1.5*oheight);
    }
}
function snowFlakeMover(evt:Event):void {
var dO:MovieClip;
var o :Object;
if(visible && parent.visible){
for (var i:int = 0; i < snowflakes.length; i++) {
    dO = snowflakes[i] as MovieClip;
    o = snowflakeProps[dO];
    dO.y += o.k;
    dO.x += o.wind;
    if (dO.y>oheight+10) {

        dO.y = -20;

    }
    if (dO.x>owidth+20) {

        dO.x = -(owidth/2)+Math.random()*(1.5*owidth);
        dO.y = -20;

    } else if (dO.x<-20) {

        dO.x= -(owidth/2)+Math.random()*(1.5*owidth);
        dO.y = -20;
    }

}
}
}

and here is the error:
