Getting `initialize': wrong number of arguments(1 for 0) (ArgumentError) for simple ruby app

This is my first ruby app. And I am a stack overflow virgin... When I run the following program:



class NameApp

def intialize(name)
@names =
end

def name_question
print "What is your name? "
answer = gets.chomp
@names += answer.to_s
puts "The number of characters in your name is " + names.length
end


def name_length
if @names.length > 25 then
print "Your name is longer than 25 characters."
else
print "Your name is too short."
end
end

end

name_app = NameApp.new("Test1")
name_app.class # => NameApp

name_app.name_question
name_app.name_length


I get this simple error message result:



name.rb:26:in `initialize': wrong number of arguments(1 for 0) (ArgumentError)
from nameapp.rb:26:in `new'
from nameapp.rb:26:in `<main>'


Can you help me trouble shoot?

            You spelled "initialize" wrong. I did that a few times too when I was starting out, and that was hard to debug. Why ruby didn't name it "init", I'll never know.
