Weird problem with RUBY and AJAX (form_remote_tag and submit_tag)

Hello,

   I am trying to implement the depot sample application of "Agile programming with rails", everrithing goes good until came to AJAX stuff,

   When I changed the button_to for submit_tag I have no HTML code generated for invoking the action using AJAX, I read the troubleshooting section and everything is OK, any Idea of what could be

happening?

The code in index.rhml is

    <% form_remote_tag :url => {:action => :add_to_cart, :id => product

} do %>

      <%= submit_tag "Add to Cart" %>     <% end %>

and the resulting form has nothing, just a couple of blank lines in the

place that should show the button.

Thank you

You left off the = on the opening <%, so the form_remote_tag line doesn't output anything.

In general, you use <% for "figuring things out", like setting a variable to the result of a calculation, and you use <%= for lines where you want the stuff in there to create some output into the html stream.

Tried also that but didn't work, still trying.

Thank you
