Pose ball with sound and action help needed

I'm trying to figure out how to make a poseball with sounds and animation to it. I've figured out how to do the animation...sort of...and I figured out how to connect the sound to it, but when I try to put in the script to stop the sound, it won't work. Can anyone help me in this scripting thing? I've looked at guides but I dunno what 1/2 the stuff means in them.
