How to say something in a concatenated string after a constant.

I don't understand why the editor is saying my code is wrong even when Xcode says I did it right. How does the treehouse editor want me to use a concatenated string.

strings.swift 
// Enter your code below
let name = "Ben"
let greeting = "Hi there, \(name)."
let finalGreeting = "\(greeting). How are you?"

The way you are doing it finalGreeting prints as "Hi there, Ben.. How are you?" (note the extra dot after Ben). I would guess that the editor sees that as an error. Try doing...

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

See if it works. Try to output the greeting with the same format as the instructions.

Hi Ben,

This:

"\(var) is interpolation"

And this:

var + " is concatenation"

Make sense?

Steve.
