Well, I've been looking at this code for about 2-3 minutes trying to figure out why it's giving you a tag mismatch, and I cannot see any reason why. The Wiki documentation says that floatsub returns a float, therefore I don't see why you're getting a tag mismatch on that line.

Are you sure that is the right line? That the error is pointing to?

Also, just for sanity sakes, can I see the code where you initialize the gInfo[gateid][dif] variable?
