title: Object has no method datepicker
body: <p>I'm getting the error <code>Uncaught TypeError: Object [object Object] has no method 'datepicker'</code> in my javascript here:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/jquery-ui.min.js"&gt;&lt;/script&gt;
  &lt;script type='text/javascript'&gt;
  $(function() {
      $("#birthday").datepicker({changeMonth: true});
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Here's the birthday item that I'm trying to add it to:</p>
  
  <pre><code>&lt;!--// BIRTHDAY //--&gt;
  &lt;li class="field"&gt;
      &lt;label for="birthday"&gt;Birthday&lt;/label&gt;
      &lt;div class="field"&gt;&lt;input type="text" id="birthday" name="birthday" value="" class="" /&gt;&lt;/div&gt;
  &lt;/li&gt;
  </code></pre>
  
  <p>As you can see, I'm including the source for jquery ui just above where I'm trying to use the datepicker. I got the URL from <a href="http://jqueryui.com/docs/Downloading_jQuery_UI">http://jqueryui.com/docs/Downloading_jQuery_UI</a> so I'm pretty sure it's a valid URL. I also tried uploading the file and linking to the local copy and I still got the same error. What else can I try?</p>
  
  <p>EDIT: </p>
  
  <p>I do have the jquery library loaded using this: <code>&lt;script type="text/javascript" src="/includes/js/jquery-1.7.2.min.js"&gt;&lt;/script&gt;</code> and verified with this bit of script:</p>
  
  <pre><code>if (jQuery) {
      alert("jQuery library is loaded!");
  }
  </code></pre>
