Hi Gustav, interpolation only needs to be used for variables or constants with stored properties let name = "Gus"

let name = "Gus"
let greeting = "Hi there, \(name)."

Hi there hasn't been declared as a constant, therefore doesn't need interpolation syntax \()

This can also be written as:

let name = "Gus"
let someGreeting = "Hi there"
let greeting = "\(someGreeting), \(name)."

But for this challenge, use the first answer. Second answer is only displayed for a deeper understanding of how interpolation works.
