Here is the exact code for your buttons:
on (release) {
unloadMovieNum (99);
loadMovieNum (“track1.swf”, 99);
}
Change the swf for the different tracks
For your off button just use:
on (release) {
unloadMovieNum (99);
}
If it still dosent’ work I’ll make you a quick FLA so you can see how it works.
