The solution is this:

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

It is worth noting that when you are doing challenges you have to name variables exactly what the challenge asks for. So by naming your variable interpolatedGreeting rather than just greeting, you would have failed the challenge even if the string interpolation code itself was correct.

Great tip I know the first few code challenges I named my variables different and it took me a bit to realize that they really need to be named exactly as specified in the instructions!

While not a real world constraint, Treehouse does want you to name the variables as and how it appears in the question. So if you name it any different it will deem your answer incorrect.

While it may not always be the convention, for most of the questions it is.
