Check line 418. I think the semicolon should be a comma.
A vague question can only get a vague answer, if any at all. This is one of the ones that can't get any answer. If the question does not contain the problem (nor the error message, which this error message is completely unhelpful), then the problem cannot be solved. It's sorta like saying I have twelve pages of algebra which works out to x = 0, y = 0, when one of the equations is x = y + 1. And then asking where I made a mistake.
I sympathise. I really do. But, as Corion implicated, we'd need to be mind-readers to get your problem.
