RAILS WILL NOT REROUTE TO NEW PAGE>>>>

running virtual rails on linux mint with rails 2.3.4

im having trouble redirecting routes so here is what ive done by
following tutorials:

i opened rails directory and created rails_test
then i ran script/server to boot mongrel
i opened another terminal and changed directory to rails_test
i then ran script/generate controller site index about help
then i went back to terminal and typed rm public/index.html to remove
index page
after this i went to rails_test folder then navigated and opened
config routes.rb
once in routes.rb i changed the following line:

map.root :controller => "welcome" to...
map.root :controller => "site"

i then got an error message stating something went wrong after opening
browser and navigating to http://localhost:3000/
i have pasted below the routes.rb file
the only thing i changed was
map.root :controller => "welcome" to......
map.root :controller => "site"

ActionController::Routing::Routes.draw do |map|
  # The priority is based upon order of creation: first created ->
highest priority.

  # Sample of regular route:
  # map.connect 'products/:id', :controller => 'catalog', :action =>
'view'
  # Keep in mind you can assign values other than :controller
and :action

  # Sample of named route:
  # map.purchase 'products/:id/purchase', :controller =>
'catalog', :action => 'purchase'
  # This route can be invoked with purchase_url(:id => product.id)

  # Sample resource route (maps HTTP verbs to controller actions
automatically):
  # map.resources :products

  # Sample resource route with options:
  # map.resources :products, :member => { :short => :get, :toggle
=> :post }, :collection => { :sold => :get }

  # Sample resource route with sub-resources:
  # map.resources :products, :has_many =>
[ :comments, :sales ], :has_one => :seller

  # Sample resource route with more complex sub-resources
  # map.resources :products do |products|
  # products.resources :comments
  # products.resources :sales, :collection => { :recent => :get }
  # end

  # Sample resource route within a namespace:
  # map.namespace :admin do |admin|
  # # Directs /admin/products/* to Admin::ProductsController (app/
controllers/admin/products_controller.rb)
  # admin.resources :products
  # end

  # You can have the root of your site routed with map.root -- just
remember to delete public/index.html.
    map.root :controller => "site"

  # See how all your routes lay out with "rake routes"

  # Install the default routes as the lowest priority.
  # Note: These default routes make all actions in every controller
accessible via GET requests. You should
  # consider removing or commenting them out if you're using named
routes and resources.
  map.connect ':controller/:action/:id'
  map.connect ':controller/:action/:id.:format'
