Hello,
I am trying to complete the first problem for Project Euler, but the test cases are not working. However, if I perform my own tests they return the desired answers. Can anyone help me fix this? I logged out of my account and closed/reopened the browser and I’m still having the same issue. Thanks!

function multiplesOf3and5(number) {
var sum = 0;
var i = 0;
for (i; i < number; i++) {
if (i%3 == 0 || i%5 == 0) {
sum = i + sum;
}
}
return true;
}
multiplesOf3and5(1000);
