**Tell us what’s happening:**

Apparently I only fail at one test (number = 1000) with my code. Does anybody see why? The result is also off by 1000…

**Your code so far**

```
function multiplesOf3and5(number) {
let i = 1;
let sum = 0;
while(i<=number){
if(i%3 == 0 || i%5 == 0){
sum = sum + i
}
i++
}
return sum;
}
console.log(multiplesOf3and5(1000));
```
