Не правильно работает _root.getBytesTotal();

[Whatsername]

onClipEvent (load) {
	_root.stop();
	var total = _root.getBytesTotal();
	var loaded;
	var percent;
	var txt;
	var txt2;
}
onClipEvent (enterFrame) {
	loaded = _root.getBytesLoaded();
	percent = Math.floor((loaded/total)*100);
	txt = percent+"%";
	txt2 = "loaded "+Math.floor(loaded/1024)+"Kb from "+Math.floor(total/1024)+" Kb";
	trace(txt);
	trace(txt2);
}
