Hey i am at the same stage. I believe the error here is that you are putting the number [3] instead of [2]. Remember the array starts with [0] as the first value
The way array indexes work, the first element of the array has index 0. So the third element of the array has index 2.
While index 3 would be wrong for this array.
Edit: also please click reset to restore the original code as you deleted one of the earlier lines of code that is needed. Then retry the step.
