Upgrade to Flash 8

[Gandalf2349]

I recently upgraded my version of Koolmoves to add support for flash 8, and was previously using only flash 6. I want to compile my movie using flash 8 to take advantage of new features, but I seem to have a problem with my actionscript code. I must be using some discontinued code in my movie. I'm assuming I'm probably making some stupid mistake, but can someone point me out here?

BTW, this code is inside a movieclip. The code itself should work, because it works fine in flash6, just I need to know what standard i must be breaking.

 loading = this._parent.getBytesLoaded();
 total = this._parent.getBytesTotal();
 percent -= (percent-((loading/total)*100))*.25;
 per = math.round(percent);
 pos = (per-100)*1.16;
 Pro._x = pos;
 Pro._width = (per*2.32);
 if (percent>99) {
           this._parent.gotoAndPlay("Intro");
    }

Also I've been having a problem where I am trying to call a function from a different frame in my main timeline. Can someone tell me how this is done?

Thank you ahead of time.
