probleempje mp3player

[edo081]

beste mensen, ik heb een mp3 speler met de volgende code:

als ik nu op het volgende nummer klik en dat blijf doen en mijn nummers zijn op dan geeft die een foutmelding "undefined" het moet dus eigenlijk zo zijn dat wanneer er geen nummers meer zijn mijn next button niet meer te gebruiken is en bij prev hetzelfde, hoe doe ik dit? of anders dat wanneer de nummers op zijn de nummers van voor af aan weer worden aangeroepen, kan iemand mij helpen kom er even niet uit..

Zet je even een "]" achter die eerste "[as" want op deze manier is je code/script heel moeilijk te lezen/ontcijferen.

Groeten,

ik heb een soortgelijk probleem met:
//feel free to use this MP3 player as you wish
//if you like it, or even if you don't, drop by my blog and hopefully get a little inspired at:
// http://www.asiabackpacker.com/blog/

//I've tried to add tons of comments to make it really easy to understand what everything does
//if you want to make any changes, or just understand how it works
//However, the only thing you have to edit is the .XML file, and the files in the MP3's folder


//generic actions involoved in loading XML and stripping whitespace
var SongsXML:XML = new XML();
SongsXML.ignoreWhite = true;
SongsXML.onLoad = loadSongsXML;
SongsXML.load("mySongs.xml");

//create a variable to hold the Sound object
var MP3ToPlay:Sound = new Sound();

//create a variable to hold the number of the song that is playing
var songNum:Number = 0;

//if "success" gets passed here, that means the loadSongsXML function executed, so the following code will execute

}

function accessSongs(){

MP3ToPlay.loadSound(SelectedSong, false);

}

stop();
en met deze xml-file:
<?xml version="1.0" standalone="yes"?>
<sounds>
<artist name = "Alan ODay">
<song file = "AngieBaby.mp3" />
<song file = "RockAndRollHeaven.mp3" />
<song file = "SkinnyGirls.mp3" />
<song file = "UndercoverAngel.mp3" />
</artist>
</sounds>

Zodra ik mijn mp3's in de daarvoor bestemde map zet en de xml file aanpas krijg ik in mijn swf file uiteindelijk een "Undefined" melding op de plaats waar normaal de titel vh nummer komt...

Weet iemand raad (met een andere movie, die ik echter niet wil gebruiken heb ik dit probleem niet)...?
