I created a movie clip with 2 frame labels with 10 frames each: part1, part2.
Each of both frame labels have 1 button.
The first button has a rollover to play part2.

The second button (the one is part2) has a Rollout that I want to go backwards until reaches the beginning of part2 one frame at the time. how can I do that?

Part1 has a animation that does not need to played twice. Thats why I need the button in the "part2" to go backwards to frame "10" or the beginning of part 2.

Thank you for your response dudes.
