Module - Extend

class Hello
  def initialize(name)
    @name = name
  end
end

module SayHello
  def say_hello
    puts "Hello #{name}"
  end
end

hello = Hello.new("Chris")
hello.extend SayHello

hello.say_hello

With these I keep getting the error " 'say_hello': undefined local variable or method 'name' for #<Hello:(HEXCODE) @name="Chris"> (NameError). Any ideas why it isn't working? It apparently works in the video "Extend and Include Part 1".

You need to include the "@" symbol in your module SayHello on the puts "Hello #{name}" line

Your line should look like this: puts "Hello #{@name}"

Your code should work then.

That's what I get for trying to do this on no sleep, didn't even realize I forgot it. Always helps to have a second set of eyes when you make a silly mistake :). Thanks!
