Flash actionScript HJÆLP

Hej allesammen.


Jeg har brug for hjælp til noget actionScript. Jeg har lavet en MP3 afspiller men kan ikk helt få den til at virke. Den kommer med fejlen:
 
Error opening URL "file:///F|/Tutorials/flash%20tuts/mp3player/undefined"

Når jeg launcher den, jeg har kodet mit actionScipt i SE | PY actionScript Editor.
Her er koden. Håber i kan se hvad der er galt.


//Setup sound object
var s:Sound = new Sound();
s.onSoundComplete = playSong;
s.setVolume(75);

var sa:Array = new Array();

//Position of music

//Load the songs XML
var xml:XML = new XML();
xml.ignoreWhite = true;
xml.onLoad = function()
{
  var nodes:Array = this.firstChild.childNodes;
  for(var i=0;i<nodes.length;i++)
  {
