Sohail,

You need to prefix a backslash character before the variables (in parentheses) in order for string interpolation to work properly:

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

It was also stuck at the second part for a while. Here is my code:

let firstValue: Int = 2

let secondValue: Int = 4

let product = firstValue * secondValue

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

let firstValue = 2

let secondValue= 4

let product = firstValue * secondValue

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

add the period at the end of product it worked for me
