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)"
```
