Hi there! At around 1:45 of this video the instructor explains how to use string interpolation. In the instructions, it is stated that the thing inside the parentheses is the name of a variable or constant. However, you've put Hi and there inside something to be interpolated. Neither of those is variables or constants.

Secondly, the string should contain a comma but is missing this. Finally, the challenge explicitly asks for the string assigned to the constant greeting to end with a full stop . Take a look:

// Enter your code below
let name = "Andrei"
let greeting = "Hi there, \(name)."

This will make a constant called name and assign "Andrei" to it. Then we make a constant named greeting and assign it the string literal "Hi there," along with the interpolated variable/constant name. The end result is that greeting will contain "Hi there, Andrei."

Hope this helps! :sparkles:

Thanks so much!
