title: Validation plugin in jQuery
body: <p>I used jQuery validation plugin in my project. But I am getting an error:</p>
  
  <blockquote>
    <p>TypeError: jQuery("#formID").validationEngine is not a function</p>
  </blockquote>
  
  <p>My calling function:</p>
  
  <pre><code>jQuery("#formID").validationEngine();
  </code></pre>
  
  <p>I am including all these scripts:</p>
  
  <pre><code>&lt;script src="js/validation/jquery-1.6.min.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="js/validation/jquery_validation.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="js/validation/validation_id.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="js/validation/jquery.validationEngine-en.js" type="text/javascript" charset="utf-8"&gt;&lt;/script&gt;
  &lt;script src="js/validation/jquery.validationEngine.js" type="text/javascript" charset="utf-8"&gt;&lt;/script&gt;
  </code></pre>
