String Interpolation Code Challenge

The format of my interpolated output string is not working! I've re-watched the video and the multiplication function is throwing me off. Still very new to Swift so I'm sure it's something silly I'm missing, but I'm stuck!

types.swift 
// Enter your code below

let firstValue = 2
let secondValue = 4

let product = 2 * 4 


let output = "\(firstValue) \(secondValue) \(product)"

Hi Nelson -

You need to use string interpolation when you are declaring your constant product and then you need to complete the sentence using string interpolation

let firstValue = 3
let secondValue = 6
let product = firstValue * secondValue

let output = "The product of \(firstValue) times \(secondValue) is \(product)"
