Interpolation

I am having difficulty solving this task:

Step 2: Using string interpolation, create a string literal that describes the operation we just performed. For example, given the following values for firstValue, secondValue and product respectively: 2, 4, 8. The string should read: "The product of 2 times 4 is 8". Assign this string to a constant named output.

What am I doing wrong?

types.swift
// Enter your code below
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
let output = "The product of 2 times 4 is 8"

The problem asks you to use string interpolation, which is basically just embedding the value of a variable/constant in a String. It's done like this:

types.swift
let firstValue = 2
let secondValue = 4
let product = firstValue * secondValue
// See how you wrap the variable/constant names in "\()"? That's how string interpolation works
let output = "The product of \(firstValue) times \(secondValue) is \(product)"
