Nested Resource - "You are Being Redirected" interim page

Hi,

A bit of a noob andtrying to get RESTful nested resources working for
the first time.
My environments is as follows:
Mac Leopard
Ruby 1.8.6
Rails 2.0.2 - standard everything, mongrel, etc.

Following various instructions & tutorials, I've got this working 99%
but apparently have made an oversight which I can't figure out that's
causing some problems.

Sorry...made an error in noting my routes.rb file. it is actually:

routes.rb

map.resources :customers do |customerS|
    customerS.resources :contacts
  end
