I am guessing that this is a continuation of this thread. Please be careful when replying to a thread to use the "Post Reply" button, not the "Post New Topic" button.

The code is also very hard to read, since all indentation is lost; you should UseCodeTags to avoid this.

Which one is line 29 of QuizClient? That's the one where the error occurs.
