ActionScript 3.0 :: SWF File Stuck At Preloader Screen

I've been trying to get this preloader working for days! I finally got it working, and now when I upload it to my site and refresh the page, the .swf file is stuck at the preloader screen.

This is my code:
//Stop Framestop();
//Create a listener to call the loading function as the movie loadsthis.loaderInfo.addEventListener (ProgressEvent.PROGRESS, loading);
//Runs when the loading progress has changedfunction loading(event:ProgressEvent):void{//Determine the percent loaded from bytesLoaded and bytesTotalvar percent:Number = event.bytesLoaded / event.bytesTotal * 100;
//Stretch a progress barprogressBar.scaleX = percent / 100;
//Set the progressText text box to the percent loadedprogressText.text = int(percent) + "%";
//When the load is finished, go to frame 2if(percent == 100){this.gotoAndStop(2);}}
