I’ve been trying to get uploadify to work, but can’t. I am following the  
tutorial by John Nunemaker.

Mine seems to be quite basic, but I just can’t figure why it wouldn’t  
work…

In my layouts/application.html.erb

```auto
  <%= javascript_include_tag 'uploadify/jquery-1.3.2.min.js' %>
  <%= javascript_include_tag 'uploadify/jquery.uploadify.v2.1.0.min.js'
%>
  <%= javascript_include_tag 'uploadify/swfobject.js' %>
  <%= javascript_include_tag :defaults %>
```

In my view,

```auto
<%- session_key_name = ActionController::Base.session_options[:key] -%>
<script type="text/javascript">
  $ = jQuery.noConflict();

  $(document).ready(function() {
      $('#upload_files').uploadify({
        'uploader' : '/javascripts/uploadify/uploadify.swf',
        'script' : '/javascripts/uploadify/uploadify.php',
        'multi' : true,
        'scriptData' : {
                          '<%= session_key_name %>' :
encodeURIComponent('<%= u cookies[session_key_name] %>'),
                          'authenticity_token' :
encodeURIComponent('<%= u form_authenticity_token if
protect_against_forgery? %>')
                        }
      });
  });
</script>

<input type="file" name="upload_files" id="upload_files" />
```

When the page is loaded I get the following error in Firebug

```auto
$("#upload_files").uploadify is not a function
```

What gives?

I could really appreciate someone’s help on this.

Thank you in advance!

Make sure the page only imports Jquery only one time.

must appear only once in the whole page (analyse the html code client  
side)

Hi:

I am facing the same problem and the jquery file has been included only  
once.  
Please suggest.

TIA,
