LoadText Class

programming flash
1

I have a textfield on the stage, and I have made a class to load in some text into it.
I just cannot get it to work :: would someone look at my code and see whats up.

package
{
	import flash.display.*;
	import flash.events.*;
	import flash.net.URLRequest;
	
	public class LoadText extends Sprite
	{
		private var txtLoader:Loader;
		private var tgt:MovieClip;
				
		public function LoadText(url:String,a:MovieClip):void
		{
			txtLoader = new Loader();
			txtLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,addText);
			txtLoader.load(new URLRequest(url));
			tgt = a;
		}
		private function addText(e:Event):void
		{
			trace(e.target.data);
		}
	}	
}

in my main timeline I write the following to access the class

var txt:LoadText = new LoadText("myText.txt, bio.area_txt);

All in all - it should be simple stuff :: but I cant see why my trace doesnt work. let alone type

tgt.text = e.target.data;

to put it in.

Any ideas?
Thanks
