Hi Sean!

You are very close!

Firstly you have put a comma where the should be a period.

var eiffelTower = (48,8582, 2.2945)

should be:

var eiffelTower = (48.8582, 2.2945)

Just a quick tip: switch statements should RETURN a value for each case. For example:

case name: return "Sean"

Also, your default value is returning an INT value not (Double, Double)

default: return (0.0, 0.0)

I hope you can figure it out from there.

If not, feel free to ask for more help!
