Hi Hope - You've mostly got the answer covered. The problem comes in during your method. Within classes, all functions become 'methods'. In a method, you're always required to call 'self', so you can't define a method without at least including that.

That being the case, you also have to explicitly say that you're calling the 'self.open', or 'self.close', and let the system know that you're calling those variables within that method.

You're on the right track! Good luck :)

class Store():
    open = 9
    close = 10

    def hours(self):
        return "We're open from {} to {}.".format(self.open, self.close)
