Rich editor

I have a script with a tinymce editor included.
But the editor doesn’t work at all.
Can somebody explain what is wrong.

In the application_helper

def in_place_rich_editor(field_id, options = {})
function = “new Ajax.InPlaceRichEditor(”
function << "’#{field_id}’, "
function << “’#{url_for(options[:url])}’”

    js_options = {}
    js_options['cancelText'] = %('#{options[:cancel_text]}') if

options[:cancel_text]
js_options[‘okText’] = %(’#{options[:save_text]}’) if
options[:save_text]
js_options[‘loadingText’] = %(’#{options[:loading_text]}’) if
options[:loading_text]
js_options[‘rows’] = options[:rows] if options[:rows]
js_options[‘cols’] = options[:cols] if options[:cols]
js_options[‘size’] = options[:size] if options[:size]
js_options[‘size’] = options[:class] if options[:class]
js_options[‘externalControl’] =
“’#{options[:external_control]}’” if options[:external_control]
js_options[‘loadTextURL’] =
“’#{url_for(options[:load_text_url])}’” if options[:load_text_url]
js_options[‘ajaxOptions’] = options[:options] if
options[:options]
js_options[‘evalScripts’] = options[:script] if options[:script]
js_options[‘callback’] = “function(form) { return
#{options[:with]} }” if options[:with]
function << (’, ’ + options_for_javascript(js_options)) unless
js_options.empty?

    function << ')'

    javascript_tag(function)
  end

In the controller

def save_editable
     flash[:notice] = "Je bent aangemeld."
 @editables = Page.find(:first, :conditions => "name =

‘Home’").editables
@editable = @editables.find(params[:id])
previous_content = @editable.html
@editable.html = params[:value]
@editable.html = previous_content unless
@editable.save
render :partial => @editable.name
end

In the view

<%= in_place_rich_editor( @edit.name,
:url => { :action => :save_editable, :id => @edit.id },
:rows => “5”, :cols => “5”)
%>

But i get only a normal clickeble text area and when i tried to save the
script nothing happened.

In the errorconsole of firefox i got tinyMCEaddMCEControl is not a
function.

I tried to use an older version of tinymce but no difference att all.
