title: Quiz - Counts Radio Button Values
body: <p>I'm trying to create a Quiz for a Spanish class. I have little experience with JavaScript, but am fairly proficient with html and CSS. I have a question and followed by three radio buttons with answers. There are two incorrect answers and a correct answer. I have 45 questions total.</p>
  
  <pre><code>&lt;form name="quiz" method="post" name="buttons" id="form" onsubmit="return totalVal()"&gt;
  
  &lt;li&gt;&lt;div class="question"&gt;¿Quién detestan la nueva casa?&lt;/div&gt;&lt;/li&gt;
  &lt;input id="answer" type="radio" name="group1" value="wrong"&gt; Josh&lt;br&gt;
  &lt;input id="answer" type="radio" name="group1" value="wrong"&gt; Amanda&lt;br&gt;
  &lt;input id="answer" type="radio" name="group1" value="correct"&gt; Josh y Amanda&lt;hr&gt;
  
  &lt;li&gt;&lt;div class="question"&gt;¿Quién es señor Dawes?&lt;/div&gt;&lt;/li&gt;
  &lt;input id="answer" type="radio" name="group2" value="wrong"&gt;Un familia amigo&lt;br&gt;
  &lt;input id="answer" type="radio" name="group2" value="wrong"&gt;Un gato&lt;br&gt;
  &lt;input id="answer" type="radio" name="group2" value="correct"&gt;Un amable joven de la agencia de bienes raíces&lt;hr&gt;
  
  &lt;li&gt;&lt;div class="question"&gt;¿Quién qué sus buscan?&lt;/div&gt;&lt;/li&gt;
  &lt;input id="answer" type="radio" name="group3" value="wrong"&gt;Josh&lt;br&gt;
  &lt;input id="answer" type="radio" name="group3" value="wrong"&gt; Petey&lt;br&gt;
  &lt;input id="answer" type="radio" name="group3" value="correct" &gt;Josh y Petey&lt;hr&gt;
  
  &lt;button class="submit" onclick="showTotalvalue();" type="submit"&gt;Submit&lt;/button&gt;&lt;/div&gt;
  </code></pre>
  
  <p>I want to use some basic Javascript to count all the "correct" radio button values and output to a new page or alert box that displays after the user clicks submit.</p>
  
  <p>I found this in my research. In my googling, I haven't been able to find a snippet of code that counts the "correct" values. The link above is the closest I've gotten. I attached the JavaScript that I changed to fit my situation from the suggestion on the other post.</p>
  
  <pre><code>totalVal = 0;
  
  // calculate the total number of corrects clicked
  
  for (y = 0; y = incorrectOfQuestion; y++) {
      var questionNo = document.getElementsByName("questions" + y);
      for (i = 0; i &lt; questionNo.length; i++) {
          if (document.myform.questions[i].checked == true) {
              totalVal = totalVal + parseInt(document.myform.questions[i].value, 45);
          }
      }
  }
  </code></pre>
  
  <p>Any assistance is greatly appreciated as I am in a time crunch! Thank you!</p>
