Message: [QUOTE="Matthew Smillie, post: 4499528"] You've made a couple of fundamental mistakes regarding how methods are defined. The basic schema is: def method_name(parameter_name) Where you can have a whole list of parameters, or none at all. See the revised (and very verbose comments. Hope this helps. matt smillie. Also, I've changed the indented to two spaces, since that's the Ruby norm. class Greeter # open class Greeter (it's not necessarily *new*) def initialize(name) # defining the initialise method, which is called when a new # object is created. The method takes one parameter, 'name'. # Example (such as: foo = Greeter.new("Mark"). @name = name # define an instance variable called '@name' and assign it # the value of the parameter 'name' end def say(phrase) # defining a new method called 'say' with a parameter # called 'phrase'. puts "#{phrase}, #{@name}" # The double quotes define a string, and the #{} sections are # used for interpolation (substitution). end end [/QUOTE]
