Multi player beginners question

Dear forum, I am trying to create a very basic multi[player interaction. You have 2 players and a ball. The ball gets cloned in by a call to the server. I am trying to send an update from the person moving the ball to the other player, but the ball gets stuck. It is both sending and receiving an update. How would I write the code for this?
