Hi there, chuck kotulka! You're doing fine but there are two separate things going on here and no, it's not a bug :smiley: Many code challenges use "strict mode" which prevents the implicit creation of a global variable. Secondly, you left the original console.log() statements in place. So those are running too.

You typed this:

 for( i = 2; i < 26; i += 2)

But in "strict mode", you would need:

 for(let  i = 2; i < 26; i += 2)

The rest of your loop is fine. When I add the let and remove the original console.log() calls, the code passes the challenge :tada:

Hope this helps! :sparkles:
