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?

Since you have not defined the method initialize for NameApp, by default, it takes zero arguments, but you passed one argument "Test1" via the constructor new.

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.
