Replace DIV with CKEditor on the Fly (ASP.NET)

Hello, I am have some trouble emulating the sample at http://nightly.ckeditor.com/7484/_samples/divreplace.html, I think this is mostly because I am using ASP.NET with a master page rather then simple HTML. My question is how can this example still be achieved? I have registered my CKEditor in the web.config of my site as I am using it in multiple places. When I attempt to run this script (gotten from the page source of the above link)

<script type="text/javascript">
   //<![CDATA[

// Uncomment the following code to test the "Timeout Loading Method".
// CKEDITOR.loadFullCoreTimeout = 5;

window.onload = function()
{
   // Listen to the double click event.
   if ( window.addEventListener )
      document.body.addEventListener( 'dblclick', onDoubleClick, false );
   else if ( window.attachEvent )
      document.body.attachEvent( 'ondblclick', onDoubleClick );

};

function onDoubleClick( ev )
{
   // Get the element which fired the event. This is not necessarily the
   // element to which the event has been attached.
   var element = ev.target || ev.srcElement;

   // Find out the div that holds this element.
   var name;
   do
   {
      element = element.parentNode;
   }
   while ( element && ( name = element.nodeName.toLowerCase() ) && ( name != 'div' || element.className.indexOf( 'editable' ) == -1 ) && name != 'body' )


   if ( name == 'div' && element.className.indexOf( 'editable' ) != -1 )
      replaceDiv( element );
}

var editor;

function replaceDiv( div )
{
   if ( editor )
      editor.destroy();

   editor = CKEDITOR.replace( div );
}

   //]]>
   </script>

I am told that CKEDITOR is unknown, unless I have an instance of CKEDITOR active on my page... which defeats the purpose.

This is an example of the page with the div swap script working.

           if (name == 'div' && element.className.indexOf('editable') != -1)
               replaceDiv(element);
       }

       var editor;

       function replaceDiv(div) {
           if (editor)
               editor.destroy();

           editor = CKEDITOR.replace(div);

</asp:Content>
<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
        <div class="editable">
        <p>
             Double Click To enter Question Statement.
         </p>
         </div>

                    <div style="left: -10000; top: -10000">
                    <CKE:CKEditorControl runat="server"/>
                    </div>
</asp:Content>

To break it just remove the CKE:CKEditorControl.
