Help with Storyline 3 game

I am hoping someone can take a look at my file and provide some insight. I created a game based on a sample on this site. The game allows users to pick money squares at the end based on how many questions they get right. I have added triggers to up the count on the variable by 1 for every right answer, and decrease it by one for every square picked. The problem is, I have a bug that I can't seem to fix. When picking squares, after about the fifth one, the variable count goes up to fifty. I've checked all my triggers and can't figure out why. Can someone please try this out for me and see if they can figure it out?

Thanks!
