I'm Newbie - Help needed badly :(

Hi there
I bought a template and couldn’t figure out the AS. The player_btn can load 4Songs but only in swf format and I’d like to change the the script to load as mp3 format but how to do I edit the script?:h:

I need help badly from you PROs.

Best Regards~

Here’s the script written

sound_but7

on(release) {

	gotoAndStop(2);
	_root.soundstatus="off";
	equalizer.gotoAndStop(2);

}

sound_but7

on(release) {

	gotoAndStop(1);
	_root.soundstatus="on";
	equalizer.gotoAndStop(1);

}

sq_sound

onClipEvent(load){
num=1;
}
on(rollOver) {
this.gotoAndPlay(“s1”);
}

on(rollOut, releaseOutside) {
this.gotoAndPlay(“s2”);
}

on(release) {
if(_root.sound<>num){
loadMovieNum(“music1.swf”,1);
_root.soundstatus=“on”;
_parent[“num”+num].gotoAndStop(2);
_parent[“num”+_root.sound].gotoAndStop(1);
_root.sound=num
_parent.gotoAndStop(1);
}

}
