I need some help figuring it out what is wrong with my code, I have been having trouble with indenting code and I think that might be the case in this exercise.

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