Note: Make sure to enter a period/full stop after your name in the final string.

let name = "martijn"
let greeting = "Hi there, \(name)." // <-- Full stop here

That is, however, not the important part. In the assignment it says: Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?".

The keyword here is concatenate. Strings can be concatenated by using the + operator. This is another way of combining strings, the other would be String Interpolation, which is how greeting was created.

let name = "martijn"
let greeting = "Hi there, \(name)."
let finalGreeting = greeting + " How are you?" // Make sure there is a space before how

Hope that helps :)
