Preloader for multiple scenes

Question

Hi, I'm trying to make a web site, I have 7 scenes and everything is working perfect. But here's my question.
When I try to make 1st scene as a preloader nothing happens. Preloader never shows up and it jumps directly to 2nd scene "Main"
Here's my code:
stop();
this.addEventListener(Event.ENTER_FRAME, loading);
function loading(e:Event):void {
          var total:Number = this.stage.loaderInfo.bytesTotal;
          var loaded:Number = this.stage.loaderInfo.bytesLoaded;
          bar_mc.scaleX = loaded/total;
          loader_txt.text = Math.floor((loaded/total)*100)+ "%";
          if (total == loaded) {
                    gotoAndPlay(1,"Main");
                    this.removeEventListener(Event.ENTER_FRAME, loading);
Also if I delete my contents in the "Main" scene and leave a single image, code works perfect.
Preloader shows up and then loads my "Main" scene.
How can I code it, as it first calculates my whole scenes, and shows my 1st scene "preloader" at the beginning.

Answer 1

I followed the tutorial, here's the code he suggested.
var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS. loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE. done);
l.load(new URLRequest("main.swf"));
function loop(e:ProgressEvent):void
          var perc:Number = e.bytesLoaded / e.bytesTotal;
          percent.text = Math.ceil(perc*100).toString();
function done(e:Event):void
          removeChildAt(0);
          percent = null;
          addChild(l);
When I try to export this, flash gives me an error with line 2 and line 3.
