Oops, try again. total([0, 3, 6]) returned 3 instead of 9

I honestly thought the code would work. I assume that the variable x represents all indexes in numbers but if the error code is saying it only returns 3, then x either isn't adding all the indexes together or does not represent all of them.

```
n = [3, 5, 7]
def total(numbers):
result = 0
for x in range(0, len(numbers)):
result = result + x
return result
```
