Um, huh? You're misunderstanding the function of this somehow. Although I don't understand quite what you're trying to say, you seem to believe one of the following:

a) That the answers are somehow in the source of the page and can just be extracted from there (which they aren't; they're stored on the server and only the number identifying the right answer for this particular question can be found in the source).
b) That the questions are always mathematical and can simply be solved by a computerized calculator (which they're not).
c) That the questions are predetermined and thus could be answered using a simple if statement in a script that hardcodes the questions/answers in, which there is not (there are no default questions and they're 100% user-customizable so there are infinitely many possibilities for questions and answers, at least as far as the server can handle).

I assure you that it is impossible to create a script that will get around NoSpam! unless that script contains the best artificial intelligence yet invented, and if it does, then it can sure as hell crack CAPTCHA as well. I guarantee that this will provide you with better spam protection than CAPTCHA ever will, at least if you use proper questions, and if you don't, that's your fault, not mine.
