preloader code

I'm using the code from this tutorial for a preloader.  Though I am not using a dynamic text field like the tutorial says.

I took the line referring to the dynamic text field out of the code, but it's still not working?

The animation has 2 frames with movie clips in each. One for the preloader and one for the main content.

Do I need to put somekind of stop or non-looping code in here so it doesn't go back to frame 1(preloader)??

this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
this.loaderInfo.addEventListener(Event.COMPLETE, onComplete);

function onProgress(e:ProgressEvent):void
{
    var loaded:Number = e.target.bytesLoaded;
    var total:Number = e.target.bytesTotal;
    var pct:Number = loaded/total;
    loader_mc.scaleX = pct;
}

function onComplete(e:Event):void
{
    nextFrame();
}
