You must call super in WacSubProfile#initialize to invoke
WacSubscribers#initialize.

I am new to ruby and try to figure out how inheritance works.
I don't get the result I expect. I marked the line of code with "#error".
What do I need to do to get it to work?

    class WacFrames
      attr_reader :wacFrameNav
      attr_reader :wacFrameDisp
      def initialize()
        @wacFrameNav = "nav"
       @wacFrameDisp = "disp"
      end
    end

    class WacSubscribers
      attr_reader :fr
      attr_reader :frame
      def initialize()
   @fr = WacFrames.new()
  @frame = @fr.wacFrameNav
      end
    end
    
    class WacSubProfile < WacSubscribers
      def initialize()
  #some code
      end
      end
    end

    another = WacSubscribers.new()
    puts another.fr #works fine
    puts another.frame #works fine
    
    test = WacSubProfile.new()
    puts test.fr #error
    puts test.frame #error

Thanks
