Help with a sound issue...please

I’ve got a slight sound problem…got a sound file attached to a button’s Down state…but I can’t get rid of the sound when a user clicks another button without using on(release) as that’s already taken by another command?

I’ve tried attaching mySound.stop(); to the each menu button so that the sound disappears when you go to another frame, but it doesn’t…what am I doing wrong? Please help me it’s driving me insane! :run:
