I keep getting the error: missing argument for parameter 'longitude' in call self.location

The full error reads: missing argument for parameter 'longitude; in call self.location=Location(latitude: Double, longitude: Double)

here is my code:

classes.swift 
struct Location {
    let latitude: Double
    let longitude: Double
}

class Business {
    let name: String
    let location: Location

    init(name: String, latitude: Double, longitude: Double) {
        self.name = name
        self.location = Location(latitude: Double, longitude: Double)
    }
}

let someBuisness = Business(name: "BusinessName", latitude: 12.0, longitude: 27.8)

Almost:

class Business {
    let name: String
    let location: Location

    init(name: String, latitude: Double, longitude: Double) {
        self.name = name
        self.location = Location(latitude: latitude, longitude: longitude)
    }
}

The second row of the init is calling the default init for Location with the values passed in to it.
