ID3 Trouble?

can anyone please help me figure out why these ID3 tags are reading back “undefined” when i preview my MP3 player.

Here’s the tag code i’m working with…

var trackInfoArray:Array;
var trackInfoTracker:Number = 0;

mySound.onID3 = function() {
trackInfoArray = new Array();
trackInfoArray[0] = "artist : " + mySound.id3.TCOM;
trackInfoArray[1] = "track : " + mySound.id3.TIT2;
trackInfoArray[2] = mySound.id3.TCOP;
trackInfoArray[3] = "track " + (curTrackNum + 1) + " of " + myLV.totalTracks;

    clearInterval(infoChangerInterv);
    infoChangerInterv = setInterval(infoChanger, 5000);
    infoChanger();
}

function infoChanger() {
trackInfo.text = trackInfoArray[trackInfoTracker];

if (trackInfoTracker == (trackInfoArray.length - 1)) {
    trackInfoTracker = 0;
} else {
    trackInfoTracker++;
}

}

function restartTrackInfo() {
infoChangerInterv = setInterval(infoChanger, 5000);
infoChanger();
}

Thanks!
