Changing the value of the preloader bar

This code is taken from the an example done by Claudio

preloader bar is exactly 100px and works correctly with the percentage value
I had a little mess around with changing the preloaders width value to 200
and it only displayed half of the preloader.

I was just wondering HOw would I change the code so that I can Have a Preloader
that is customable to my design. e.g say if my preloader is 150 px long how would
I make it work in relation to a percentage value. I am complete newbie to action script
so any help would be most thank full.


this.createEmptyMovieClip(“temp”, 1000);
function preload() {
this.transition.txtPercentage = “”;
temp.onEnterFrame = function() {
var t = this._parent.content.getBytesTotal(), l =
var percent = Math.round(l*100/t);
if (!isNaN(t)) {
if (t>0 & l == t) {
this._parent.transition.txtPercentage = “Complete”;
delete this.onEnterFrame;
} else {
this._parent.transition.loadBar._width = percent;
this._parent.transition.txtPercentage = percent+" %";
