Where are you calling display_counter from? I would have expected it to be from the view, in which case put the method display_counter in a view helper not in the controller. Pass it the value @times_visited. So in the view: <%= display_counter @times_visited %> Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
