Error Generated with Preloader! Please Help!

programming flash

I am getting the following error when I try to publish my preloader: Scene 1, Layer ‘preloader actions’, Frame 1, Line 9 1119: Access of possibly undefined property star through a reference with static type flash.display:Loader.
Can someone please let me know what I am doing wrong? Below is my code for the preloader…

stop();

loader.star.addEventListener(Event.ENTER_FRAME, updateLoader);


loader.star.scaleX = 0;


function updateLoader(event):void {
	var prog:Number = loaderInfo.bytesLoaded / loaderInfo.bytesTotal;
	loader.star.scaleX = prog;
	//trace("loader scale = " + loader.bar.scaleX);
	if ( prog == 1 ){
		loader.star.removeEventListener(Event.ENTER_FRAME, updateLoader);
		//goto the next frame where the content is.
		gotoAndStop(2);
	}
}
