title: Uncaught TypeError Object [object Object] has no method 'datepicker'
body: <p>I am getting this error when my page loads:</p>

  <p>I thought it may have to do with a Jquery conflict, so I add <code>$.noConflict();</code> before the function call.  Still I am not sure how can we see if there is Jquery conflict present in our page or not.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;script src="../js/jquery-1.9.1.min.js"&gt;&lt;/script&gt;
  &lt;script src="../js/jquery-ui-1.10.2.custom.min.js"&gt;&lt;/script&gt;
  
  &lt;!-- 
    &lt;script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"&gt;&lt;/script&gt; 
  --&gt;
  
  &lt;link type="text/css" href="jquery.datepick.css" rel="stylesheet"&gt;
  &lt;script type="text/javascript" src="jquery.datepick.js"&gt;&lt;/script&gt;
  
  &lt;?php
    echo "&lt;script&gt;User();&lt;/script&gt;";
  ?&gt;
  
  &lt;link rel="stylesheet" 
    href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" /&gt;
  
  &lt;script&gt;
  
    $(function() {
      $( "#fast" ).datepicker();
    });
  
  &lt;/script&gt;
  
  &lt;script&gt;
    $(function() {
      $('#modal').draggable({ handle: "p" });
    });
  &lt;/script&gt;
  </code></pre>
  
  <p>My major question is how we can see if conflicts exist or not and how to remove them.  What does this error mean and how can I fix it?</p>
