You've almost got it except for a couple things. First off, you're using a comma after the greeting in the finalGreeting instead of a period. Often times these challenges are picky and are looking for something very specific.

The main issue is that the second challenge has asked you to use string concatenation whereas you only used string interpolation. I prefer using string interpolation wherever possible, but you must use string concatenation at least once for this challenge. There are a number of solutions that will get the challenge to pass.

The following are correct solutions (among other):

let name = "Troy"
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting)." + "How are You?"

let name = "Troy"
let greeting = "Hi there, \(name)"
let finalGreeting = greeting + ". How are You?"

The following, will not pass, because it does not use string concatenation:

let name = "Troy"
let greeting = "Hi there, \(name)"
let finalGreeting = "\(greeting). How are You?"
