Music is on loop but starts over itself when i change frame!

hey,

I recently followed this tutorial.
(http://www.entheosweb.com/Flash/flash_sound_button.asp)

I followed it exactly and the button worked fine with the music,

but then i stated to add keyframes, it works fine carys on playing on every keyframe i go to, but the problem is when i go back to the first keyframe the music still goes on which is good, but its starts again over the one thats already playing!!

I belive it ahs something to do with the actionscript but im new to this so any help would be appreaciated.

thanks:D
