I've been working on this program recently and its been blowing up with errors, every time I work through a bug, more surface. Now I keep getting incompatible type errors at the spots I marked out. If someone could help me sort it out or point me in the right direction, that would be great. WARNING:HUGE AMOUNTS OF CODE TO FOLLOW.
