I got it working . All I have to do is add scoring and and a game over /restart section to my game.
I also have to improve the ball and paddle movement. but at least I am almost there.
I have spent a month this cause I only get to spend 1 to 2 hrs a week on this and I am brand new to programming
It seems as if name.collision can’t be name.collision2
see my code below
