Update textbox xml

programming flash
1

i have an MP3 player with a playlist using an external xml file. This all works fine but i also have dynamic textboxes showing what song title and artist is playing. These update fine when the user clicks back and forward buttons but the problem i am having is that i can not get the textBoxes to update when the user clicks on a song from the playlist. Here is my code -


import fl.events.ListEvent;

var my_songs:XMLList;
var my_total:Number;
var my_sound:Sound;
var my_channel:SoundChannel;
var current_song:Number = 0;
var song_position:Number;
var song_paused:Boolean;

var myXMLLoader:URLLoader = new URLLoader();
myXMLLoader.load(new URLRequest("playlist.xml"));
myXMLLoader.addEventListener(Event.COMPLETE, processXML);

function processXML(evt:Event):void
{
    var myXML:XML = new XML(evt.currentTarget.data);
    var item:Object;
    my_songs = myXML.SONG;
    playSong(0);               
        
        for each(var prop:XML in myXML.SONG){
                item = new Object();
                item.label = prop.@ARTIST;
                item.data = prop.@URL;
                playList.addItem(item);
        }
        my_sound = new Sound();
        my_sound.load(new URLRequest(playList.getItemAt(0).data));
}

playList.addEventListener(ListEvent.ITEM_CLICK, onClick);
function onClick(evt:ListEvent):void
{
    var item:Object = evt.item;
    my_channel.stop();
    my_sound = new Sound();
    my_sound.load(new URLRequest(item.data));
    my_channel = my_sound.play();
}

function playSong(mySong:Number):void
{
    var myTitle = my_songs[mySong].@TITLE;
    var myArtist = my_songs[mySong].@ARTIST;
    var myURL = my_songs[mySong].@URL;
    title_txt.text = myTitle;
    artist_txt.text = myArtist;
    
    if(my_channel)
    {
        my_channel.stop();
    }
    my_sound = new Sound();
    my_sound.load(new URLRequest(myURL));
    my_channel = my_sound.play();
    my_channel.addEventListener(Event.SOUND_COMPLETE, nextSong); 
}

next_btn.addEventListener(MouseEvent.CLICK, nextSong);
function nextSong(evt:Event):void
{
    current_song++;
    if(current_song > 9)
    {
        current_song = 0;
    }
    playSong(current_song);
}

prev_btn.addEventListener(MouseEvent.CLICK, prevSong);
function prevSong(evt:MouseEvent):void
{
    current_song--;
    if(current_song < 0)
    {
        current_song = 9;
    }
    playSong(current_song);
}

pause_btn.addEventListener(MouseEvent.CLICK, pauseSong);
function pauseSong(evt:MouseEvent):void
{
    song_position = my_channel.position;
    my_channel.stop();
    song_paused=true;
}

play_btn.addEventListener(MouseEvent.CLICK, play_Song);
function play_Song(evt:MouseEvent):void
{
    if (song_paused)
    {
        my_channel = my_sound.play(song_position);
        song_paused = false;
    }
    else if (!my_channel)
    {
        playSong(current_song);
    }
}

Any ideas?
