Support Animation and Rigging

Hi
I am following this tutorial https://www.youtube.com/watch?v=iYL9w6xsZ6g
Everything is working fine till 12:50 when I am hitting ALT+A to play the animation. The button (The active) is disappearing in the box (The passive) and some of the buttons are falling through it. Please I need urgent help.

Managed to solve the problem by giving the passive object more width on the z axe.
