You almost have it correct

let name: String = "Jeff"
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting)" + "How are you?"

Thanks!

For the 'greeting' constant, you assigned a string value by using string interpolation which is perfectly fine. For the 'finalGreeting' constant however, it will read "Hi there, Aiden + How are you". For concatenation you want to type ' greeting + " How are you?" or correctly by string interpolation ' "(greeting) How are you?" Hope this helps!
