[color=black][font=Arial]Hi ppl,[/font][/color]

Can someone help me please? I want to be able to get this preloader working in my application.

Baiscally I would like to call it in from 2 movieclips. So I tried this code:

[indent][font=Courier New][color=black]bytes_loaded = Math.round(_root.screenMC.preloaderMC.getBytesLoaded());

bytes_total = Math.round(_root.screenMC.preloaderMC.getBytesTotal());
getPercent = bytes_loaded/bytes_total;
_root.screenMC.preloaderMC.loadBar._width = getPercent100;
_root.screenMC.preloaderMC.loadText = Math.round(getPercent
100)+"%";
if (bytes_loaded == bytes_total) {
_root.screenMC.preloaderMC.gotoAndStop(3);
}[/color][/font]

[/indent][font=Courier New]Yet it never worked can someone tell me what I done wrong please?[/font]
