Not quite sure where I'm going wrong

I need to console.log all even #'s from 2-24... could someone help me understand what I'm doing wrong here? Thank you! Code is as follows:

function evens() { for(i=2; i<=24; i += 2); console.log(i) }

evens();

script.js 
function evens() {
  for(i=2; i<=24; i += 2);
  console.log(i)
}

evens();
index.html

Hi Juliann,

You're on the right track, but the challenge wants you to write a for loop only (you also wrote a function). Just delete everything that is not directly part of the for loop and you're good to go.

Challenges are VERY specific and VERY picky. If you add something that isn't asked for, it will not pass you.

for (var i = 2; i <= 24; i += 2) {
  console.log(i);
}

Welcome to Treehouse. Keep Coding! :)

This passed the challenge:

for (i = 2; i <= 24; i += 2){
  console.log(i);
}

Hope this helps...
