title: HTML and JavaScript: different values depending on the radio button
body: <p>I have a pretty simple problem, but I can't find the answer online, so now I'll ask here. I hope someone can help. <br/>
  I have 2 questions, and beneath each of those, I have a group of radio buttons, each with 3 buttons: 'Enig', 'Neutral' or 'Uenig'. I want to assign each option a value of 1, 0, or -1, and depending on what is chosen, give the question or group that value. <br/>
  This applies to both of the 2 groups of radio buttons. <br/>
  At last, I want to display the total score of the 2 questions (q1+q2), when a button is pressed. <br/>
  I really hope someone knows how to do this, it would really be a great help!</p>
