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

There's a glitch. This generates an error about the name of the constant (should be "product") but if I change the constant name to product i get an error to say it should be "output". Please fix

types.swift
// Enter your code below
let firstValue: Int = 12
let secondValue: Int = 14
let output: String = "The product of \(firstValue) times \(secondValue) is \(firstValue*secondValue)"

Hey Chris,

this is not a bug/glitch. The challenge wants you to solve this in two steps, first creating the product constant where you store the product of firstValue * second Value, then in the second step you should output all the constants in the string in the constant output.

Like this:

// Enter your code below
let firstValue: Int = 12
let secondValue: Int = 14
let product: Int = firstValue * secondValue
let output: String = "The product of \(firstValue) times \(secondValue) is \(product)"

Also note that you don't have to use type annotation here to explicitly specify the type of the constants, but if you want to that's okay as well! :)

So it should also work like this:

// Enter your code below
let firstValue = 12
let secondValue = 14
let product = firstValue * secondValue
let output = "The product of \(firstValue) times \(secondValue) is \(product)"
