Yeah, like i said, the Admin's will be able to find the problem I'd say or the developer, send them a copy of the error, your username and what you did to make the error occur, then they can test it and stuff and find the flaw. It's usually something silly in the code. The Division by Zero sounds interesting though, check your security settings or something and try again, but still notify the admins, could be a point of attack on it or something.
