I did not clearly understand the requirement for the external argument label. Could someone help me ?

I did not clearly understand the requirement for the external argument label. Could someone help me find what am I missing here. Thanks a lot for your support!

functions.swift 
// Enter your code below

func coordinates(forLocation location : String) -> (latitude: Double, longitude: Double){
switch location {
case "Eiffel Tower":
    return (48.8582,2.2945 )
case "Great Pyramid":
    return (29.9792,31.1344 )
case "Sydney Opera House":
    return (33.8587,151.2140 )
default:
    return (0.0, 0.0)
}
}

let effielTower = coordinates(forLocation : "Eiffel Tower")

The challenge asks for a function with an external name for and a local name of location so you just need to change "forLocation" to "for". You also don't need any names in the return tuple

// Enter your code below
func coordinates(for location : String) -> (Double, Double){
switch location {
case "Eiffel Tower":
    return (48.8582,2.2945 )
case "Great Pyramid":
    return (29.9792,31.1344 )
case "Sydney Opera House":
    return (33.8587,151.2140 )
default:
    return (0.0, 0.0)
}
}

let effielTower = coordinates(forn : "Eiffel Tower")
