Problem

I got a problem in copying the symbol and make the mouse click. Mouse click can work at the same timeline, but I put my animation in different symbol and at the different timeline. And the bad things is I cannot move my animation in to another symbol. So I still find the way and I cannot move to the second page, I need to fix this very fast.

This is what I want, after the first page gone, then the second page come out. But in this stage, the problem is I cannot move the object in to the Happy Symbol, so I confused, if I copy, then the animation will gone too.
