  <p>I give a <code>true</code> statement in every right answer so if user choose an answer with <code>true</code> statement it should be adding 1 points to the score and print the score, the problem is I get this warning <code>(function () { [native code] })</code> when I'm trying to print the score, the score should be 0 at first</p>
