title: Show Field if Radio Button is Selected
body: <p>I'm attempting to get the Website URL field on <a href="http://myfrugaltech.com/dev/savoo/register/" rel="nofollow">this page</a> to display only when the previous question has the radio button "Yes" selected. I've searched and tried a few code examples, but they aren't working. Does anyone have any suggestions for me?</p>
  
  <p>Thanks in advance!</p>
  
  <pre><code>&lt;div class="editfield"&gt;
  &lt;div class="radio"&gt;
      &lt;span class="label"&gt;Do you have your own website? (required)&lt;/span&gt;
      &lt;div id="field_8"&gt;&lt;label&gt;&lt;input type="radio" name="field_8" id="option_9" value="Yes"&gt; Yes&lt;/label&gt;&lt;label&gt;&lt;input type="radio" name="field_8" id="option_10" value="No"&gt; No&lt;/label&gt;&lt;/div&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  
  &lt;div class="editfield"&gt;
  &lt;label for="field_19"&gt;Website URL &lt;/label&gt;
  &lt;input type="text" name="field_19" id="field_19" value="" /&gt;
  &lt;/div&gt;
  </code></pre>
