Subject: Re: Module issue

I plan move the "require" up top, once I've got my stuff straight.

Okay, I needed the "self." in the Module def.

< in ahs.rb >
module Ahs
   class CreditCard
    def self.test2
      puts "\n\nself.CreditCard.test2 fired\n\n"
    end
  end
  def self.test
    puts "\n\nself.test fired\n\n"
  end
end

< in offer_renewal_controller.rb >
   Ahs.test
   Ahs.CreditCard.test2

Result:
self.test fired
undefined method `CreditCard' for Ahs:Module [exception thrown]

What's wrong with the second statement?

Thanks helping,
Jason
