MC drag/undrag sound and load

Hey, I could really use some help here if anyone has some xtra time

I need to make these green buttons “float” around randomly within the white box (I read the random motion tut, and got that to work except I can’t add other actions to it) So what I need is to allow random movement…onRollover I need the button to start drag, when the user moves quickly out of the button, I need stop drag. Voet already got that to pretty much work, but when I try to load that swf into another movie, all that happens is that the buttons actually just dissappear. I would also like an mp3 to play when the user first rolls over the button
OH By the way, the buttons are really just MC’s…I’ve posted the fla I would really appreciate any help.
