Dynamic textfield!please help!

hi

[LEFT] I need to load some swfs inside a movieclip with preloader.So on the stage I have some movieclips (linked to “product1” class) which will act as buttons to load particular swf, a holder mc and a dynamic textfield(named-“percent”) for preloading stuff.My problem is how to reffer “percent” text field from the “product1” class?
[/LEFT]

my code is like this…

package
{
import flash.display.;
import flash.events.
;
import flash.net.;
import caurina.transitions.
;
import flash.text.*;

public class Product1 extends MovieClip
{
        
    
    
    public function Product1()
    {
        this.addEventListener(MouseEvent.CLICK,tick1);
        this.addEventListener(MouseEvent.ROLL_OVER,over);
        this.addEventListener(MouseEvent.ROLL_OUT,out);
        this.buttonMode=true;
                    
    }

    function over(e:MouseEvent):void
    {
        Tweener.addTween(MovieClip(this).bullet_mc,{rotationX:360,time:1});
        Tweener.addTween(MovieClip(this).bullet_mc,{x:-20,time:.5});
    }
    
    function out(e:MouseEvent):void
    {
        Tweener.addTween(MovieClip(this).bullet_mc,{rotationX:0,time:1});
        Tweener.addTween(MovieClip(this).bullet_mc,{x:-10,time:.5,transition:"easeInOutBounce"});
    }
        
    
    function tick1(e:MouseEvent)
    {
        
        var mc_loader = new Loader();
        mc_loader.load(new URLRequest(e.target.name+"_big.swf"));
        mc_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
        mc_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
        MovieClip(this.parent).holder_mc.addChild(mc_loader);
        
    }
        function loop(e:ProgressEvent)
        {
            var perc:Number;
            perc =e.bytesLoaded / e.bytesTotal;
            /[SIZE=2]**[COLOR=Red]/I am stucking at this position, now how to reffer "percent" from here??[/COLOR]**[/SIZE]
            percent.text = Math.round(perc*100).toString();            
            addChild(percent);
                        
        }
            
        function done(e:Event):void
        {
            
            
            removeChild(percent);    
            
        }
        
        
    
}

thanks in advance
