Rails - Apr 2008 - NoMethodError in StoreController#add_to_cart

I''m trying to set up the Depot app from Agile Web Development and I
got this error after C1 - Creating a Cart.

The exact error looks like this:

-------------------------------------------------------------------
NoMethodError in StoreController#add_to_cart

You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.<<

E:/InstantRails/rails_apps/depot/app/models/cart.rb:9:in `add_product''
E:/InstantRails/rails_apps/depot/app/controllers/store_controller.rb:
8:in `add_to_cart''
------------------------------------------------------------------

The contents of cart.rb:
---------------------------------------------
class Cart
	attr_reader :items

	def initialize
		@items = []
	end

	def add_product(product)
		@itmes << product
		debugger
	end
end
--------------------------------------------------
The contents of store_controller.rb
-------------------------------------------------------------------------------
class StoreController < ApplicationController
  def index
	  @products = Product.find_products_for_sale
  end
  def add_to_cart
	  @cart = find_cart
	  product = Product.find(params[:id])
	  @cart.add_product(product)
	  debugger
  end

  private

  def find_cart
	  session[:cart] ||=Cart.new
  end
end
---------------------------------------------------------------------------------
What could be the problem?
