Buttons, sounds and looping problems

Hi,

I’m new here, been trying to get to grips with Flash.

I have 3 buttons, one has an electricity sound when you mouseover, which loops, this is good for an electricty sound effect.

The other two though need to only play the sound sample once. I don’t want these to loop, but I want the animations on the buttons to loop.

What do I do:hr:

Many thanks.
