Animated buttons methods

okay, so i am working on the project and i was wondering if there was a different way to create a button to “swell” (meaning, once you rollover a button, it will grow slighty bigger, and then when you rollout of it, it will shrink back to its orginal size).

my question, is there anyway to do this with out having to like try an line up the movie clip with the button, and doing a tellTarget thing to play the movie clip.

i though there was a way to do it within the over state of the button, but apparently that only works one way cause when you rollout of it, it will just go back to frame 1 of the movie clip.

so, if anyone knows of a better way to do this, i’m all for it.

thanks!
