The first one works fine. The challenge is to REMOVE 'answer' and 'good_answer' from the code.

That's where I'm getting locked up, since it seems I need to store or at least check 'reply' with each pass. Otherwise, my 'while' is just going over the same question over and over, rather than moving from one to the next.

Was able to get it to through all the questions, but when the 'yes/no' failed, the "Please answer yes or no" was being counted as a question and then skipping the next one in line.
