Instructions for this challenge are not too clear and I am continuously getting errors.

Step 1: Declare a constant named product and assign the result of multiplying firstValue and secondValue together. (To multiply two values, a and b, we write a * b).

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.

types.swift
```// Enter your code below
let firstValue = 5
let secondValue = 4
let sum = firstValue * secondValue
let product = sum
``` Hi Stephen, It looks like there may be a bit of confusion on the question. For step 1, the problem is asking you to assign the product of firstValue and secondValue to a constant named product. What you currently have is you're assigning the product of firstValue and secondValue to a constant named sum.

As far as the second part goes, you'll need to do create a constant named output and assign it a string that has something like the following:

```let name = "Stephen"
let a = "hello \(name)"
``` Hi Stephen,

You are mostly correct, you simply forgot to concatenate your final string. I have attached the code below! Hope this helps!

let firstValue = 3 let secondValue = 6

let product = firstValue * secondValue

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