Completely stumped here. Extend Customer class with tracking module.

Surely you only have to use include Tracking?

Angela, in your Customer class, you don't need the Constant Resolution operator (::) on the extend statement.

class Customer
    extend Tracking
    attr_accessor :name

    def initialize(name)
        @name = name
    end
end
