Cannot complete Challenge task 2/2 in Swift 3 Basics

I have checked the code in XCode and it is correct. Not sure what is wrong......

strings.swift 
// Enter your code below

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

The challenge instructions specify that you have to use string concatenation when creating the finalGreeting constant. String concatenation is where you combine separate strings using the + operator. The technique you currently use in your solution is called string interpolation. The resulting string will end up being the same regardless of what technique you use, but the challenge will only accept string concatenation for this task, since Treehouse is testing your knowledge in the various ways of combining strings and variables/constants.

So to solve the challenge you have to combine the greeting constant and the " How are you?" string using the + operator, which you were thought about in the video preceding this challenge.
