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

Question

I am suppose to write interpolated string that says something but its not working UGH.
My current code is:
let firstValue = 4
let secondValue = 5
let product = firstValue * secondValue
let output = "("The product of 4 times 5 is") (product)"
types.swift
// Enter your code below
let firstValue = 4
let secondValue = 5
let product = firstValue * secondValue
let output = "\("The product of 4 times 5 is") \(product)"

Hey Dawson,
Phillip already gave you a hint. You can interpolate variables in a string by writing them inside of \(). You did that correctly with product, now you just have to do the same with firstValue and secondValue and not with the string around them.
Like this:
```swift
// Enter your code below
let firstValue = 4
let secondValue = 5
let product = firstValue * secondValue
let output = "The product of (firstValue) times (secondValue) is (product)"
```

Thank you @Phillip Paik (https://teamtreehouse.com/phillippaik) and @Tobias Helmrich (https://teamtreehouse.com/tobiashelmrich)! I understand now thanks to you two awesome dudes

The output should be:
"The product of (firstValue) times (secondValue) is (product)"
( blah blah) Only variables and arrays and constants or math should go inside the "blah blah"
For regular strings, you keep that outside of them.
