Character Rig Animation Doesn't Work With Script Activation?

I want a Character rig to do an animation when you touch a brick, and vanish after the animation is complete, but something went wrong in my script! Can somebody help me? I have a video link to the entire thing and the script, please help! The video link is down below, thanks!
