Rollout button help

Hi,

I’d like to make a button, but also with rollout state, thus I have to make it from MovieClips.

All I have done is that incorporated three MC (up_mc, rollover_mc, rollout_mc) into a btn_mc, and applied some AS code to call the different mc-s at different mouse states.

I attached an fla made with MX to show how I imagined… but still does not work.

Please help.

Thanks!
