How do i only make a button active if at least one yes?
<p>So i have this structure    </p>

<pre><code>&lt;div class="accordionContent"&gt;
&lt;form action="/make_requests" class="make_request" method="post"&gt;&lt;div style="margin:0;padding:0;display:inline"&gt;&lt;input name="authenticity_token" type="hidden" /&gt;&lt;/div&gt;                                                         
&lt;tr&gt;
    &lt;td&gt;Enter Sandman&lt;/td&gt;
    &lt;td&gt;2&lt;/td&gt;

    &lt;td class="money"&gt;$0.00&lt;/td&gt;
    &lt;td&gt;    
            &lt;input class="yes_please" id="group_7,1,2_yes" name="group[7,1,2]" type="radio" value="yes" /&gt;
        Yes
            &lt;input checked="checked" id="group_7,1,2_no" name="group[7,1,2]" type="radio" value="no" /&gt;
        No
    &lt;/td&gt;
&lt;tr&gt;
    &lt;td&gt;Fade to Black&lt;/td&gt;
    &lt;td&gt;2&lt;/td&gt;
    &lt;td class="money"&gt;$0.00&lt;/td&gt;
    &lt;td&gt;    
            &lt;input class="yes_please" id="group_3,6_yes" name="group[3,6]" type="radio" value="yes" /&gt;
        Yes
            &lt;input checked="checked" id="group_3,6_no" name="group[3,6]" type="radio" value="no" /&gt;
        No
    &lt;/td&gt;
&lt;/tr&gt;
  &lt;tr&gt;&lt;td&gt;&lt;input id="make_requests" name="commit" type="submit" value="Add to Set" /&gt;&lt;/td&gt;&lt;td&gt;&lt;span class="band_notice"&gt;Set Added&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;
&lt;/form&gt;
</code></pre>

<p>I need to only make the input enabled if at least one of the radio buttons is yes ...any ideas how to do this in jQuery</p>
