Well, you should fix it then.

Seriously, you're not being charged per character typed here. Going out of your way to make your descriptions as terse as possible isn't going to help you. If you want anyone to help you fix a problem, you need to provide a proper description of the problem, along with the relevant parts of your code, and the full details of the error(s) you're experiencing.
