Thank you for your help. I tried your suggestions along with many other things, but it's still not working exactly how I want it.
The points are being displayed, but they are cumulative, and I don't want that. For example, if there are three collisions on the screen, the points should be 300, and then later if there are two collisions on the screen, the points should be 200, not 500, which is what is happening now.
How do I make my points not cumulative?
