Preloader not working in IE, works great in Safari and Firefox

FLASH MX/1.0
I am wondering if anyone knows why this preloader does not work in Internet Explorer but works great in Safari and Firefox? I got the the preloader script from this tutorial:
http://www.kirupa.com/developer/mx/percentagepreloader.htm

This is pretty much the only script used:
bytes_loaded = Math.round(this.getBytesLoaded());
bytes_total = Math.round(this.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
this.loadBar._width = getPercent100;
this.loadText = Math.round(getPercent
100)+"%";
if (bytes_loaded == bytes_total) {
this.gotoAndPlay(3);
}

Is there something missing that would make it work in IE?
Thanks in advance for any ideas.
BTW, here is the link to the site I am working on, you can test it in different browsers and see for yourself:
