title: JQUERY: Multiplying input elements select box and radio boxes and hidden inputs
body: <p>Evening, </p>
  
  <p>I'm tyring to multiply different input elements but for some reason it's giving me a NAND error. As the user selects, check or modify the values of any element. This should change the total amount.</p>

  <pre><code>&lt;select name="select"&gt;
  &lt;option value="1"&gt;1&lt;/option&gt;
  &lt;option value="2"&gt;2&lt;/option&gt;
  &lt;option value="3"&gt;3&lt;/option&gt;
  &lt;/select&gt;
  &lt;input name="radio" type="radio" id="radio" value="10" tvalue="100" /&gt;
  &lt;input name="radio" type="radio" id="radio" value="20" tvalue="200" /&gt;
  &lt;label id="Total"&gt;&lt;/label&gt;
  </code></pre>
  
  <p>Also if you take a look at the jsfiddle code i have tvalue=100 and the other is =200 as a custom attributes, how would I access that instead of accessing the regular html value.</p>
  
  <p>Thank you. </p>
