Tell us what’s happening:

Your code so far


function multiplesOf3and5(number) {
// Good luck!
let sum = 0;
for(i=1; i<number;i++){
  if(i%3==0 || i%5==0){
    sum = sum+i;
  }
}
return sum ;
}

Hello jucarlospm, welcome to the forum!

When I copy/paste your code into the challenge, I get the error "ReferenceError: i is not defined". Are you getting this error?

If so, then you just need to figure out why i is not defined. Remember, you have to use let, var, or const to declare a variable.
