Hey, I tryed the first problem of the Euler project, but for some reason the code bellow is not give me the correct answer:

```
def multiple_sum(multiple=3):
x = 0
for n in range(0, 1000):
if not (n % multiple):
x += n
return x
print multiple_sum(5) + multiple_sum(3)
```

It is giving me 266333, where it should be giving me 266168

The problem discription is here:

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.

Find the sum of all the multiples of 3 or 5 below 1000.

Edit: GOD DAMN THAT RANGE FUNCTION, SHOULD HAVE ADDED ONE TO INCLUDE 1000.

However, this doesn't fix my problem. I'm still hopelessly confused on that front.
