kroeg my friend, this whole process is easy, I can't imagine the time it took you to type all of that jazz out. AND it's what everyone else has already said ~
I"M DOING all of those things !! lol, that's where the problem comes in, I know what the functions are, I know what the grid is, I type everything correctly, but they're still not working, I even just used your exact example down to the T, just incase i was overlooking something!

still not working.. thanks a ton though for at least having the kindness to reply :P, and no i'm not THAT dense that i need pictures LOL, or maybe i am ?
P.s.
psst! add pictures me no understand! j/k
In sincerity
