programming flash

Need help with the following code, I have created an as3 audio player and wanting to add a progress bar to the page which shows the user the progress of the track as they listen, not percentage loaded.

any help appreciated, my progress bar is called “progressBar”

here is my code::

var jukeboxX:XML;
var songList:XMLList;
var currentIndex:Number = 0;
var currentSound:Sound;

var firstSong:Sound = new Sound();
var sc:SoundChannel;
currentSound = firstSong;

var loader:URLLoader = new URLLoader();
loader.addEventListener(Event.COMPLETE, onComplete);
loader.load(new URLRequest(“songs.xml”));

function onComplete(e:Event):void
{
jukeboxX = new XML(loader.data);
songList = jukeboxX.song;
//trace(songList);

firstSong.load(new URLRequest(songList[currentIndex].url));
sc = firstSong.play();
title_txt.text = songList[currentIndex].author;
quote_txt.text = songList[currentIndex].title;

stop_btn.addEventListener(MouseEvent.CLICK, stopSound);
play_btn.addEventListener(MouseEvent.CLICK, playSound);
next_btn.addEventListener(MouseEvent.CLICK, nextSound);
prev_btn.addEventListener(MouseEvent.CLICK, prevSound);

}
function stopSound(e:Event):void
{
sc.stop();
play_btn.addEventListener(MouseEvent.CLICK, playSound);

}
function playSound(e:Event):void
{
sc.stop();
sc = currentSound.play();
play_btn.removeEventListener(MouseEvent.CLICK, playSound);

}
function nextSound(e:Event):void
{
var nextSound:Sound = new Sound();
sc.stop();
currentSound = nextSound;
if (currentIndex < songList.length() - 1)
{
currentIndex++;
}
else
{
currentIndex = 0;
}
nextSound.load(new URLRequest(songList[currentIndex].url));
sc = nextSound.play();
title_txt.text = songList[currentIndex].author;
quote_txt.text = songList[currentIndex].title;

}
function prevSound(e:Event):void
{
var prevSound:Sound = new Sound();
sc.stop();
currentSound = prevSound;
if (currentIndex > 0)
{
currentIndex–;
}
else
{
currentIndex = songList.length() - 1;
}
prevSound.load(new URLRequest(songList[currentIndex].url));
sc = prevSound.play();
title_txt.text = songList[currentIndex].author;
quote_txt.text = songList[currentIndex].title;
}
