# Project Euler Problems 1 to 100 - Problem 1: Multiples of 3 and 5

Tell us what’s happening:
returning zero('s the hero)

``````function multiplesOf3and5(number) {
let sum = 0;
for(let i = 1; i > number; i++) {
if(i % 3 === 0) {
sum += i;
}
if(i % 5 === 0){
sum += i;
}
}
return sum;
}
console.log(multiplesOf3and5(49));
``````

This does not seem right.

`i >= number; `
also returns zero

You want to run this loop only when i is bigger than num?

guess i am not greater than a number after all v^<>

Pay attention to the if…else statement. You are missing ‘else’ {} in order to get the correct results. You have already got the direction for the direction of iteration through the for loop.

thanks yeah i changed it to a single if with"
`||`
in between so it worked " >
