jquery validation
<p>I have a poll with a couple a questions. Here is html code </p>

<pre><code>&lt;form id="pool"&gt;
 &lt;div class="questions&gt;
  &lt;input type="radio" name="sex"&gt;Male
  &lt;input type="radio" name="sex"&gt;Female
 &lt;/div&gt;

 &lt;div class="questions&gt;
  &lt;input type="radio" name="hair"&gt;Brown
  &lt;input type="radio" name="hair"&gt;Blonde
 &lt;/div&gt;

 .... a lot of qestions div's
&lt;/form&gt;
</code></pre>

<p>What to do so after the form is submitted to be sure that there is a checked radio button in all div`s ?</p>
