Methods within structs

I'm not sure why this isn't working. Any suggestions?

struct Person {
    let firstName: String
    let lastName: String

    func fullName(x: String, y: String) -> String {
        return x + " " + y

The method is not supposed to take any parameters. It's supposed to use the firstName and lastName properties that already exists in the struct.

So just remove the parameters and replace x and y with firstName and lastName.
