Can someone please help me with this file?

http://www.edleedesign.com/transitionEffect.zip

I downloaded this effect transition off of istockphoto (great for those of us not super advanced in actionscript) and I'd like to do either 1 of 2 things.

1. figure out why this script doesn't work in Flash 8

onClipEvent (enterFrame) {
if (_parent.doneLoading == 0) {
total = _parent._parent.getBytesTotal();
isloaded = _parent._parent.getBytesLoaded();
p = 100*(isLoaded/total);
_parent.bytes = int(isloaded/1000) add " KB of " add int(total/1000) add " KB";
_parent.percent = int(p) add "% LOADED";
_parent.bar._xscale = p;
if (Number(p)>Number(99)) {
_parent._parent.gotoAndPlay(Number(2));
_parent.gotoAndStop("off");
_parent.doneLoading = 1;
} else {
_parent._parent.gotoAndPlay(Number(1));
}
}
}

it's calling the following script errors

**Error** Symbol=preloader, layer=background, frame=1:Line 6: Syntax error.
_parent.bytes = int(isloaded/1000) add " KB of " add int(total/1000) add " KB";

**Error** Symbol=preloader, layer=background, frame=1:Line 7: Syntax error.
_parent.percent = int(p) add "% LOADED";

or

2. How to get this preloader out of my movie completely. Because I tried using my own preloader but it's not working because I think there is some other code somewhere that called the above forementioned preloader code.

thanks so much for all the help
