I’m building an mp3 player that finally seems like it’s coming together. Back and forth works fine now. So I tried taking it to the next level by adding those bouncing bars that you see in most music players like winamp. Problem is. I just followed a tutorial, and by themselves the bars work fine but when I try to encase them in a function that I want to execute once the music is loaded the bars only jump once and then they stay flat. Any idea what’s wrong.

var t = 0;
var l = 0;

this.createTextField("status_txt", this.getNextHighestDepth(), 72, 630, 100, 22);
// create a new Sound object
var my_sound:Sound = new Sound();
musictext.text = "loading";
// if the sound loads, play it; if not, trace failure loading
my_sound.onLoad = function(success:Boolean) {
if (success) {
my_sound.start();
musictext.text = "music on";
_root.preloader._visible = false;
antiShane();
} else {
status_txt.text = "Sound failed";
}
};
// load the sound
myCount = 0;
totCount = 1;
mySongs = ['song1.mp3', 'song2.mp3', 'song3.mp3'];
nextTrack = function () {
my_sound.loadSound(mySongs[myCount], false);
this.onEnterFrame = function() {
//trace(t);
//trace(p);
//trace(l);
t = my_sound.getBytesTotal();
l = my_sound.getBytesLoaded();
if ((t>0) && (t != null)) {
p = (l/t)*100;
p = int(p)+1;
preloader.gotoAndStop(p);
}
if (l == t) {
delete this.onEnterFrame;

The bars are encased in the function ‘anitShane’ cause of an internal joke in case anyone was wondering. thx in advance.
