**Tell us what’s happening:**

It’s an exercise.

requirements:

addFive should be a function

addFive should be a function

sum should be equal to 8

Returned value from addFive should be undefined

Inside of your functions, add 5 to the sum variable

Returned value from addFive should be undefined

Inside of your functions, add 5 to the sum variable

I don’t know what’s wrong with my code because it gives me an error on ‘sum should be equal to 8’.

**Your code so far**

```
// Example
var sum = 8;
function addThree() {
sum = sum + 3;
}
// Only change code below this line
function addFive(sum){
sum = sum + 5;
}
// Only change code above this line
var returnedValue = addFive(3);
```
