Am I incorrectly creating interpolated strings?

I thought I was correctly following the syntax for interpolated strings shown in the examples in the video, but I keep getting an error message pop up for this code challenge saying "Make sure the value for greeting is an interpolated string."

What is wrong with my code for the constant greeting?

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

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

Like this.

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

You write your string literally normally. That's the stuff between the "" quotes. Anytime you want to insert a value in there, like we did with the constant "name" above you pop the value inside of the () brackets. Because we want it to understand the bracket we escape the opening bracket with the \, otherwise it will think you just want to include the brackets in your string literal.

Hope this helps. :)

Thank you so much! That was way simpler than I thought.
