Nav menu problem

Hey all,

Been working on this idea I had for a ring-shaped nav menu: user clicks on link and the ring rotates so that that link is on top. I know I’m forgetting something obvious, but I can’t figure out how to essentially say “when you click this button, play until the frame where it is at the top.” At the moment the best I can do is gotoAndStop, which isn’t really any good at all. Can anyone refresh my memory? (Be sure to check out the fla so you see how I have it organized - although that can certainly be changed!)

Many thanks!
