AS3 Preloader Percentage

[FIRESCAPE]

So I have been working on a website and building a preloader. The preloader is it's own swf that loads an xml and loads the swf files named in that. The current animation is a timeline based swf of just a swirling graphic that loads into the main preloader swf. My problem now is that the clients and some other people who have reviewed the website want it to display the percent so that they know where the loading process is at. I have no idea where to do this in my code now since I'm not the AS3 expert. I thought I would post my code and see if anyone could point me into the right direction. Thanks!

You are using customclasses, which somebody has made. You need to ask the developer of those classes.
