Cup Game issue
 

Hello.
I am making a cup game for my final project where the player guesses where the ball is hidden under a cup. The game is basically completed except for one bug. The ball only reveals itself after I make a wrong guess and choose the right cup. The ball does not show up when I pick the correct cup on the first try. This is driving me insane. Please tell me what I am doing wrong. I need help ASAP
