Transitions Between External SWFs Tutorial

I am trying to use this tutorial (http://www.kirupa.com/developer/mx2004/transitions.htm) to create some smooth transitions on a site I am currently working on. So far I have not been able to make it work even doing things exactly as they are described in the tutorial. But what I would like to do is use .loadClip instead of loadMovie to load my .swf’s. I think I have the correct code in the first frame of the root movies timeline:

_root.currMovie = “2fbp_home”;

var containerLoad:MovieClipLoader = new MovieClipLoader();
containerLoad.loadClip (_root.currMovie+".swf",_root.container);

stop();

What I needed help with is what the correct code would be for my buttons to load new sections and what I would need in the last frame of the timeline for the .swf’s I’m loading. I’ve tried everything I know to try and have had no luck so if anyone can shed some light on this I would appreciate it.

Thanks,
Chris
