MovieClip Transitions [Flash MX]

I have multiple movie clips, each are brought up on level 1 with attachMovie code on each button (I have tried on different levels, but it didn’t work). I am trying to get them to play the “in” transition animation when its button is clicked, as well as the “out” transition animation when a different button is clicked. It won’t play the “out” animation though.

I have 19 different movieclips like this, so I also need to know how to make it so that no matter what order the buttons are clicked, it has know to play the “out” transition on the last/correct movieclip.

I have attached file that is very similar to mine (same code and such), but with less movieclips. Please help!
