'include' statements usually go inside a class -- essentially, 'include Amatch' adjusts the class you're defining by adding the methods from the Amatch module. A 'require' statement, on the other hand, just tells Ruby to bring in the contents of the filename you specify. So you probably want this kind of thing: require 'amatch' class Seller include Amatch # Rest of your class definition here end Try that and see if it resolves the error. If not, there may be a problem finding the amatch file itself. Chris Try -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
