jquery why doesn't this text show up
<p>I am trying to teach myself jquery, (not so successfully so far)  why doesn't the div with id fill get updated when i click submit?</p>

<pre><code>&lt;script type="text/javascript" src="jquery-1.7.1.min.js"&gt;&lt;/script&gt;              
&lt;script type="text/javascript"&gt;
  $(document).ready(function(){
    $("input#go").click(function(){
      $("div#fill").load('test1.txt');
    });
  });
&lt;/script&gt;
&lt;/head&gt;
&lt;body&gt;                            
  &lt;form name="login"&gt; 
    &lt;label&gt;&lt;strong&gt;Administrative Login &lt;/strong&gt;&lt;/label&gt;                              
    &lt;p&gt;Username:&lt;/p&gt;                
    &lt;input name="username" type="text" id="username" /&gt;            
    &lt;p&gt;Password&lt;/p&gt;               
    &lt;input name="password" type="password" id="password" /&gt;
    &lt;br&gt;                     
    &lt;input type="Submit" id="go"&gt;
    &lt;div id="fill"&gt;&lt;/div&gt;
</code></pre>
