  def initialize(title, first, middle, last)
    @title = title
    @first = first
    @middle = middle
    @last = last
  end
end

name = Name.new ("Mr", "Ally", "", "Cuccurullo")

puts name.title = " " +
     name.first + " " +
     name.middle+ " " +
     name.last

Alphonse,

It seems your issue is likely the space between Name.new and the (.

Give this a shot:

name = Name.new("Mr", "Ally", "", "Cuccurullo")

From at first glance, your issue is with the attr_reader and attr_writer

  attr_reader(:title, :first, :middle, :Last)
  attr_writer(:title)

You've got parenthesis that should not be there, you've also got a capital L in last and you've got :title in both reader and writer, it should be in just writer (or accessor if you've reached that part).

Instead, your code should read.

class Name

  attr_reader :first, :middle, :last
  attr_accessor :title

  def initialize(title, first, middle, last)
    @title = title
    @first = first
    @middle = middle
    @last = last
  end
end

name = Name.new ("Mr", "Ally", "", "Cuccurullo")

puts name.title = " " +
     name.first + " " +
     name.middle+ " " +
     name.last

     puts "title: #{name.title} "
     name.title = "dr"
     puts "title: #{name.title} "

I know this is old, but I wanted to just see if those solutions actually solved the problem. The solution, I think, is actually where it says

puts name.title = " " +
     name.first + " " +
     name.middle+ " " +
     name.last

I think you meant to put a '+' rather than the '=' . That should fix it, no?
