**Tell us what’s happening:**

`Honestly, I can't get through with this challenge, it keeps saying " Once both functions have ran, the sum should be equal to 8" how can I do that? I tried adding both functions together and nothing. I tried creating another variable and adding both function it is still nothing. I don't understand where I went wrong`

**Your code so far**

```
// Example
var sum = 0;
function addThree() {
sum = sum + 3;
}
// Only change code below this line
function addFive(){
var sum = sum + 5;
}
// Only change code above this line
addThree();
addFive();
```
