Music loads.."Off" button works but "On" doesn't?

I’ve got the index page running fine. When opened the music loads the way it should. I created buttons to allow for “on” and “off” choices for the user. The “Off” button works fine, but if I click “on” nothing happens. Here’s the link to the page;

Here’s the actionscript i’m using. It’s on the sounds frame, not the buttons themselves.

bgSound = new Sound(this);
bgSound.attachSound(“rebel”);
musicon_btn.enabled=false;

musicoff_btn.onRelease = function() {
bgSound.stop();
musicon_btn.enabled=true;
musicoff_btn.enabled=false;
};
musicon_btn.onRelease = function() {
bgSound.start();
musicon_btn.enabled=false;
musicoff_btn.enabled=true;
};
