**Tell us what’s happening:**

I believe the test case for 1000 is incorrect. The system won’t accept my solution that results in a value of “234168”, whereas it wants “233168”.

**Your code so far**

```
function multiplesOf3and5(number) {
// Good luck!
let result = 0;
for(let i = 3; i <= number; i++){
if(i % 3 == 0 || i % 5 == 0){
result += i;
}
}
return result;
}
multiplesOf3and5(1000);
```
