Hi Daulet,

The challenge is telling you to set the constant greeting to the value of "Hi there, " followed by (using interpolation) the value in name.

You've demonstrated in your last line that you know how to use string interpolation, you just need to make sure that the result ends up in the right constant.

You should end up with just two lines:

  • one declaring the constant name and assigning the value of your name to it (you already have this exactly right);
  • one declaring the constant greeting and combining (using interpolation) the string literal "Hi there, " and the contents of name.

Hope that helps

let name = "Daulet" let greeting = "Hi there, " let combination = "(greeting) +( name)"

let entropolatedCombination = combination

// This one is right
