Modifying Kirupas Volume Slider

I am working with this: http://www.kirupa.com/developer/mx/volume_slider.htm

I want to do 2 things. I would like to start the music playing with the slider somewhere in the middle. Secondly, i would like to be able to change tracks. (External mp3s, not embedded) I tried a simple test of loading a different mp3 when you click a button but it didn’t work.

on (release) {
mySound.loadSound(“music/nora2.mp3”, false);
}

Not that i know how, but will any need to set up an array to be able to cycle through the tracks.

any ideas?
thanks

I think i figured it out how to change tracks with some AS i found in a book.

changeTrack(0);
trackname = “select play”;
currentTrack = 0;
music = new Array(“nora1.mp3”,“nora2.mp3”);
// change track
function changeTrack(number){
if (number >= 0 && number < music.length){
currentTrack = number;
slideSound.stop();
slideSound = new Sound();
slideSound.loadSound(“music/”+ music[number], true);
trackname = currentTrack + 1;
slideSound.onSoundComplete = function (){
changeTrack(currentTrack + 1);
}
}
}
