I get an error trying to run the last part of this Variables video

class Fede
  def initialize(title, first_name, middle_name, last_name)
    @title = title
    @first_name = first_name
    @middle_name = middle_name
    @last_name = last_name
  end
  def title
     @title
  end

  def first_name
     @first_name
  end

  def middle_name 
     @middle_name
    end

  def last_name
     @last_name
    end
 end

name = Fede.new("Mr")
puts name.title + " " +
name.first_name + " " +
name.middle_name + " " +
name.last_name

And this is the Error message I get

name.rb:2:in `initialize': wrong number of arguments (1 for 4)
 (ArgumentError)                                              
        from name.rb:25:in `new'                              
        from name.rb:25:in `<main>'

Please, help

I kinda solved this by thinking about it and doing this, but is this mentioned in the video?

name = Fede.new("Mr", "Barack", "Hussain", "Obama")

I answered this here:

https://teamtreehouse.com/forum/for-me-this-code-doesnt-pass-unless-you-pass-in-the-new-4-parameters

There was a cutscene where I'm pretty sure more stuff got changed than we see in the video.

The line near the bottom should say:

name = Fede.new("Mr", "Jason", "", "Seifer")

Yeah, Jason doesn't show this part and it just has to be there :). Otherwise the code will never work.
