I think I get what you are trying to say, but I can print out the array with no problems, so the whole thing should be defined, correct? So I am not sure how I would go about fixing this.

    You can print out undefined values. (Though if you have warnings enabled, that kind of behaviour will earn you one.)

    I'm not entirely sure how you'd fix it. Some self-contained code which doesn't rely on files from your system that I don't have on my computer might help.
