What is wrong with the following code? I keep getting an end of input error for line 26 but everything looks correct.

module Inventoryable
    def stock_count
        @stock_count ||= 0
    end

    def stock_count=(number)
        @stock_count = number
    end
end

class Shirt
    include Inventoryable
    attr_accessor :attributes

    def initialize(attributes)
        @attributes = attributes
    end
end

Class Pant
    attr_accessor :attributes

    def initialize(attributes)
        @attributes = attributes
    end
end

Class Accessory
    attr_accessor :attributes

    def initialize(attributes)
        @attributes = attributes
    end
end

shirt1 = Shirt.new(name: "MTF", size: "L")
shirt2 = Shirt.new(name: "MTF", size: "M")

shirt1.stock_count = 10

puts "Shirt 1 stock count: %s" % shirt1.stock_count
puts "Shirt 2 stock count: %s" % shirt2.stock_count
