Show hide menu with rollover/rollout problem

Hi all,
The attached is my sample of show hide menu , but the problem is i used a movie clip to make rollover and then second mc will come out.And in that second movie I have buttons (:crying:that’s the problem indeed I cannot click the buttons ) , and also on that second movie ,when I rollout that second movie it has to go inside or disapper.so because of the rollout on second mc the inside buttons cannot click.

So somebody help me pls! I’m in urgent.thanks in advance.
