Declare a constant named finalGreeting, and concatenate the value of greeting with the string literal " How are you?"

My code is correct in xcode but the treehouse program is not accepting it? Help:

strings.swift 
// Enter your code below
let name = "Pasan" 
let greeting = "Hi there"

let interpolatedgreeting = "\(greeting),\(name)."

let finalGreeting = "How are you?"
let concatenatedGreeting = (greeting) + ","+name+"."+(finalGreeting)

Hi there, Sterling! Now you've almost got it. Now string concatenation is when you stick something together. In swift it's when you close a string with a quotation mark then do a + then do antoher set of quotation marks. For e.g

strings.swift 
let firstName = "Sterling"
let greeting = "Hello there, Sterling." + "How are you?"

So your thing should look something like this:

strings.swift 
// Enter your code below
let name = "Pasan" 

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

let finalGreeting = "\(greeting)" + "How are you?"

If this doesn't work just comment and i'll help. Good luck!
