Hey Fatih,

means that id doesn’t exist on carouselImages[counter].

So what do you expect carouselImages[counter] to be?
Where does carouselImages come from?
What is carouselImages[counter] before the if?

Check your logic for setting counter. In at least one situation when the event listener is triggered carouselImages[counter] is not defined. If carouselImages is an array and counter is an integer, then you are probably running into an index out of bounds error.
