jQuery alert box not working
<p>I have a tiny bit of code thats meant to show a javascript alert when a select list is changed value, but it doesnt seem to be working, could anyone give me a hand and let me know where im going wrong.</p>

<pre><code>&lt;script type="text/javascript"&gt;
$(document).ready(function(){
    $("#sources").change(function(e) {
        alert('This is what an alert message looks like.');
    });
});
</code></pre>

<p></p>

<p>HTML for the select is as follows:</p>

<pre><code>&lt;select name="sources" id="sources" multiple="multiple"&gt;
  &lt;option value=""&gt;please select&lt;/option&gt;
  &lt;option value="5"&gt;Seek&lt;/option&gt;
  &lt;option value="6"&gt;friends&lt;/option&gt;
&lt;/select&gt;
</code></pre>
