Evan, can you explain >it a bit better? Maybe show how it is supposed to look in the overall code? Breaking it down slightly, compared to the other replies you've received: You start by labeling each row (1, 2, 3, 4, etc). Odd-numbered rows we colour white, even-numbered rows we colour green. We already have a convenient label for our rows (the variable $i in the original example), we just have to decide when it's odd and when it's even. Even numbers are divisible exactly by 2, odd numbers leave a remainder. To find the remainder after a division, we use the mod (%) operator. 2 % 2 = 0 3 % 2 = 1 4 % 2 = 0 5 % 2 = 1 etc. if ($i % 2 == 1) { echo ("white"); } else { echo ("green"); } The ?: stuff is just short-hand for if/else.
