Final Game

This week our final games are due. I've got most of mine done, but for some reason this one seen won't work. It is the one with the bathtub and water heaters. When the player gets the answer wrong and they replay the scene, it will say that the correct one is wrong as well. I think that the wrong answers are not disappearing correctly. I have decided I'm just going to re-link everything and find where the problem is.
