jQuery multi level selector does not work but .children does
<p>I have this javascript code which works fine</p>

<pre><code>var QuestionID = panel.siblings('.QuestionIDWrapper').children('input[type=hidden]').val();
</code></pre>

<p>but if I convert it to use a multi level jQuery selector like this:</p>

<pre><code>var QuestionID = panel.siblings('.QuestionIDWrapper input[type=hidden]').val();
</code></pre>

<p>I don't get any value in QuestionID.</p>
