There's just one problem with your code. In finalGreeting, you encased the variable greeting within the double quotes, meaning that the computer doesn't know that it should replace greeting with the value of the variable greeting.

It's really easy to fix this:

let finalGreeting = greeting + " How are you?"

greeting is a variable that you declared in Step 1 so you need to use string interpolation 

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