title: How can I add a confirmation alert on radio button selection?
body: <p>At the end of a form I have the code below which asks a user to select yes or no radio buttons. Often, the wrong option is selected and I want to limit this by adding a 'Are you sure' confirmation statement/alert. The options should remain the same, just a further yes/no I guess. </p>
  
  <pre><code>&lt;td class="t1_head"&gt;Keep with Tier 3?&lt;/td&gt;
  &lt;td class="t1"&gt;
    &lt;input type="radio" name="open" value="Yes" checked&gt; Yes &amp;nbsp; 
    &lt;input type="radio" name="open" value="No"&gt; No &amp;nbsp; 
    &lt;i&gt;(This overrides the above scheduling)&lt;/i&gt;
  &lt;/td&gt;
  </code></pre>
  
  <p>Any help, much appreciated.</p>
