Cannot figure out what makes this string invalid

Greeting is supposed to be an interpolated string that incorporates the following:

  • "Hi there, "
  • Constant named name
  • "."

Any assistance would be much appreciated

strings.swift 
// Enter your code below

let name = "Clay Walter"

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

He uses the wrong syntax which throws an Error. If you want to incorporate strings which are declared to constants or variables incorporate into other strings, you have to use the syntax like in the example above. You can also declare hi there to a separate variable and incorporate two variables to pass the challenge. I'm sure there are also other ways to do it but sometimes the challenge only concentrates on one particular way to solve it. Below you have an example how to do it with two variables 

let name = "Cley Walter"
let extend = "Hi there"

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