Hi there! I feel like you might be stuck on step 1, but I'm not entirely sure. First, there is no instruction by the challenge to make a constant named interpolatedGreeting, so you can safely remove that line. The greeting variable should contain the string "Hi there, " and the interpolated value of the name variable. We use a backslash and a set of parentheses to tell Swift to take whatever value is in that variable and put it where those parentheses are. So the solution to the first step would be:

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

If you were to now print the value of greeting, it would print out "Hi there, Ronald", because it is taking the value stored in name and inserting it at that spot in the string.

Hope this helps! :sparkles:
