Hi Marguerite,

Your function is trying to return a variable "hash" that doesn't exist.

Inside of the function, your first line Hash.new(create_shopping_list) is creating a hash, then trying to insert create_shopping_list into it. For an empty hash, just use Hash.new().

After you create the empty hash, you need to return it. you can do this in two lines (by assigning the new hash to a variable) or one line (return the new hash directly):

def create_shopping_list
  h = Hash.new()
  return h
end

or

def create_shopping_list
  return Hash.new()
end

Let me know if you have any questions!

Thanks, Stephen
