I'm a bit lost as to how to make this log 12 times

Shouldn't the "i <= 24; i +=2" part make this log 12 times?

what have I missed?

Thanks. Beginning to think JS is beyond me.

for ( var i = 0; i <= 24; i += 2 ); {

Syntax syntax syntax. Here's what it should be. In trade, can you tell me the difference between mine and yours?

for (var i=2; i<=24; i+=2){

omg thanks so much - i knew i had it right, just couldn't work it out!!

(the semicolon was inside the curly braces)

Set your 'var i = 0;' to 'var i = 2;'. That should solve your problem. Just remember that the initial 'i' in the for loop is your beginning point, and will be counted as one of the loop rotations. I hope this makes sense! P.S. I put that first comment in the wrong section. My apologies!

Also, (if you haven't already) remember to remove all of the other 'console.log' functions written into the exercise before submitting your code. That's what burned me on that one :)

JS is fickle, but don't give up. You may need to learn a different way than how it is taught here. Look at some other resources that teach JS or have practice exercises for you to work with.

Hi, thanks Ben and Brandon, I've changed the 0 to a 2 and this still says it only logs once. I think I initially did have the "2" as the inital "i" value, but changed it because it wouldn't work.

I might try restarting chrome and trying again.

you will also want the last number to be 26 not 24.
