Rails - Apr 2006 - Clearing text_field_tag -- Help PLEASE

I''m trying to clear the input fields on an Ajax form.  Unfortunately,
I''ve tried this just about every way I can
think of and instead of clearing the fields, it''s clearing pretty much
the whole page.  I would ***really*** appreciate some help!

The page has a form that allows the entry of two fields.  The form exists inside
a <div> with id=entry.  When the user clicks the button, a new line is
added to the page inside a <div> with id=ingredient_list.  The user can
add as many lines as they want.  I want to clear the fields each time they click
the button. What''s happening instead is that the entry <div> and
everything above it on the page is getting wiped out.  The code is below.  Any
ideas?

Thanks in advance,
Bill

--- Here''s _entry_form.rhtml ---
<%= form_remote_tag(:update => ''ingredient_list'',
          :url => {:action => :add_ingredient},
          :position => ''bottom'',
          :after => {:action => :clear_entry}) %>
   Name:
   <%= text_field_tag :name %>
   Amount:
   <%= text_field_tag :qty %>
   <%= submit_tag ''Add Ingredient'' %>
<%= end_form_tag %>

--- and here''s the clear_entry action in the controller ----
def clear_entry
   render :update do |page|
      page.entry.name.value = ''''
      page.entry.qty.value = ''''
   end
end
