Jonny,

You're close here, it's just a matter of watching what you do with your variable 'i', and how long you allow the loop to run. But, you have the correct syntax, which is great!

If you need to print every EVEN number between 2 and 24, there are a couple of things we need to change in your condition.

1) The value of 'i' might as well start at 2, since that is where you want to begin logging it to the console.

2) You will want to make your condition run until 'i' is equal to 24, so change your 11 to 24.

3) Since we want to log every even number and we're not obligated to do anything with the uneven numbers, we can just increase the value of 'i' by 2 every time so we're only even ever bothering to look at the even numbers!

So, the end result would be:

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

Open up your developer tools, go to the Console tab, copy and paste that code snippet in, and you'll see what you're looking for :)

Happy coding!

I've used a radically different approach, but for some reason it doesn't work inside the code challenge window. It works fine though in workspaces. Any comments?

for ( var i=2; i<= 24; i++ ) {
  var counter;
  counter = i / 2;
  if ( Number.isInteger(counter) ) {
  document.write(i +'<br>');
  }
}
