Random Movie

Hey

Me again :expressionless:
Right this is the actionscript ive got to load the mp3

if (percent == 100) {
gotoAndStop(3);
_root.contents.loadMovie("home.swf");
_root.music.loadMovie("mp3.swf");
} else {
gotoAndPlay(1);
}

I would like to load a random mp3, like mp31 mp32 mp33 ect… so different tracks are loaded

I ve looked up the random movie load tutorial but feel it dont help me as ive followed the kirupa tutorial on a full flash site, so it loads it within the movie from a instant named “music”

How can i randomize the loading in the instant?
