attempting ajax file upload

I have this basic code in place and it is giving me an: "undefined local variable or method `end_form_tag' for #<ActionView::Base:0x41a2094>"

Note sure why I am getting the error as it is straight from:

view:

<%= form_remote_tag(:url => { :controller => "image_demo", :action => "create" }, :html => {:multipart => true}) %>         <b>Picture:</b>&nbsp;         <%= file_field_tag "asset" %>&nbsp;         <%= submit_tag "Upload" %>&nbsp;     <%= end_form_tag %>

remote_uploads.rb in lib directory:

module ActionView   module Helpers     module PrototypeHelper       #alias_method :form_remote_tag_old, :form_remote_tag       def form_remote_tag(options = {}, &block)         unless options[:html] && options[:html][:multipart]            form_remote_tag_old(options, &block)         else           uid = "a#{Time.now.to_f.hash}"           <<-STR           enctype="multipart/form-data" target="#{uid}" #{%(onsubmit="# {options[:loading]}") if options[:loading]}           >           STR

        end       end     end   end end

I have this basic code in place and it is giving me an: "undefined local variable or method `end_form_tag' for #<ActionView::Base:0x41a2094>"

Because end_form_tag was removed from rails 2.0

Ok, I changed to this but it is posting normally and not ajax for some reason. i see in the source that it is supposed to do an ajax submit.

<% form_remote_tag(:url => { :controller => “image_demo”, :action => “create” }, :html => {:multipart => true}) do %>

			<b>Picture:</b>&nbsp;

			<%= file_field_tag "asset" %>&nbsp;

			<%= submit_tag "Upload" %>&nbsp;

	<% end %>

Stumped, the ajax submit works but does not pass the file param for some reason.

<iframe name="upload_file" id="upload_file" style="width:1px;height: 1px;border:0px"></iframe>     <% fields_for :file, :html => { :multipart => true, :target=>"upload_file" } do %>       <b>Picture:</b>&nbsp;       <%= file_field_tag :upload %>&nbsp;       <%= submit_to_remote 'up',"Upload", :method=>'post', :url => { :controller => "rfi", :action => "sendfile", :id => @rfi }, :target=>"upload_file" %>&nbsp;     <% end %>
