Actionscript 3.0 :: Preloader Finishes At Last Frame Of Movie?

I just followed the Preloader AS3 tut, and it works! Unlike the other sites

I have Flash CS4 AS3, and when the preloader is finished, it takes me to the end of my movie.

I'm a total beginner at this, since I've only been using Flash for about two days now , but I learn extremely fast !

In very simple terms, please explain how I can start the movie from the beginning when the preloader is done.

Also I had problems locating the URL to the swf. I kept getting "can't locate URL" when I inserted "bones.swf" for the URL request. I had to paste my files into the folder created in the tutorial for it to work. What is the difference between the folder I created and the one created in the tutorial that allowed AS to recognize the URL?

Here's my script:

var l:Loader = new Loader();
l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loop);
l.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
l.load(new URLRequest("bones.swf"));
