Hi Jon, On the chance that you have not yet gone through the labs on Locales and Object Oriented Programming, you may find clarity in some of the examples that they provide. The Locales lab would be the first one to explore as it provides a good foundation for the content of the Object Oriented Programming lab.
Hope this helps.
