Help! Stuck in refractor challenge

Don't know why I keep on getting stuck. When I run my code in my VS Code, it works fine. However, it throws an error in Treehouse when I run the code. Please help!

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

script.js 
console.log(2);
console.log(4);
console.log(6);
console.log(8);
console.log(10);
console.log(12);
console.log(14);
console.log(16);
console.log(18);
console.log(20);
console.log(22);
console.log(24);

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

Hello,

The exercise is asking you to delete the redundant code, so just delete the console.log calls and leave the Loop which is the efficient way to log numbers from 2 to 24 in increments of 2:

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

That's the same answer I have and it still came out wrong.

Really, just those 2 lines, because I tested it on the challenge editor and it passed

All I had to do was erase all the console logs and then it worked!! Wish I did that in the beginning. Challenge solved.
