Hai Bui

I understand your point of view and I'm not against any of you. I just thought that the asker didn't divide the prize fairly. My answer is short, but informative enough to solve the problem. The asker didn't manage to fix it because she overlooked some files, then she saw your answer with same solution (nothing more in my opinion), checked the files again and found it... that doesn't mean your answer deserved the full prize... I don't think so.
I hope we have some methods to rate the askers. For example, downvote askers who provide too little information, never response or vote unfairly...
