`Eq` is a type class, and type class names are capitalized (like types and constructors). Changing `eq` to `Eq` should get you past that error. Conversely, in ```hs SimpleEnigma = SimpleEnigma rotor1 rotor2 rotor3 reflectorB offsets SteckeredEnigma = SteckeredEnigma rotor1 rotor2 rotor3 reflectorB offsets steckerB ``` you'll need to change the things you're defining to start with a lowercase letter. (What you have is doubly wrong: it's invalid to declare a variable with a capitalized name, and even if it weren't, `SimpleEnigma` and `SteckeredEnigma` are already defined as the constructors of `Enigma`.)
