title: Why is jqueryUI datepicker throwing an error?
body: <p>I am trying out jqueryUI, but firebug catches the following error on this script:</p>
  
  <pre><code>$(function(){$("#date").datepicker()});
  </code></pre>
  
  <p>The firebug error reads:</p>
  
  <pre><code>$("#date").datepicker is not a function
  </code></pre>
  
  <p>On my html, the "date" id looks like this:</p>
  
  <pre><code>&lt;input type="text" name="date" id="date" &gt;
  </code></pre>
  
  <p>NB: I have used the correct JqueryUI css/js scripts on the  section</p>
  
  <p>Nothing is executing...</p>
