Auto_complete not completing

Here is what I have done.

  1. In controller: auto_complete_for :search, :string
  2. Layouts/search.rhtml <%=javascript_include_tag :defaults %>
  3. Views/search: <%= text_field_with_auto_complete ‘search’,
    ‘string’, :size => 35 %>

Any idea what I am missing?

Thank you,
Lynn
