**Tell us what’s happening:**

I have coded these and I am not sure how to make it to where the `sum([1], 0)`

should equal 0. and * `sum([2, 3, 4, 5], 3)`

should equal 9. passes. What am I missing that I need to put in or take out?

**Your code so far**

```
function sum(arr, n) {
// Only change code below this line
if (n<=0){
return 1;
} else {
return sum(arr, n-1)*arr[n-1]
}
// Only change code above this line
}
```
