alice-teacher Pong Game

[Eric Hillstrom]

I have a student you created the world using the following tutorial from
Duke:

http://ckjh.cksd.wednet.edu/staff/charlesp/Computer%20Programming/Alice%202.0/04%20Topic%20Tutorials/Level%20III/Alice%20Pong/alicePong.pdf

He is having trouble getting the paddles to move. How can this be remedied?

Also, how do you increase the ball speed?
Code attached

Thanks

Eric
