How to pass challenge task 1 of structs and enums?

How do you... You need to only have the newValue parameter for the isGreater function.

I assume it's easy, but I'm having trouble understanding what they mean.

enum Coin: Int {
    case Penny = 1, Nickel = 5, Dime = 10, Quarter = 25 

    func isGreater(currentValue: Coin, newValue: Coin) -> Bool {
        return currentValue.rawValue > newValue.rawValue

make use of it inside your function. However, that's ok, since you can use self.rawValue instead of currentValue.rawValue.

Give it a try and let us know if this explanation helped. If not, we can take it from there.
