The string literal being assigned to output must be an interpolated string that evaluates firstValue, secondValue

Why is this not working?

types.swift 
let firstValue: Int = 100
let secondValue: Int = 200
let product = (firstValue*secondValue)
let output: String = "The product of \(firstValue) times \(secondValue) is \(product)."

Hi Kevin, Excellent solution, delete the full stop . at the end of your String, and the code will pass.

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