    the example in the link is using a 10 by 12 sheet ... your problem is using a 3 by 5 sheet.

    are you saying that you are not able to change the numbers?

    Oh no, I got it. I wrote that before I saw your reply. It would be pretty bad if I didn't know how to substitute and apply! Thanks so much though! That site was a real help! =)
