Ok, I give up.
I got it to highlight and even move, but the 2 on the left move at different increments as the two on the right, the two on the right will move 2 pixils while the ones on the left move 3 or 4 or 5, or up one and down another.
I'll do it the way I've been doing it, one tile at a time.
Need a degree in computer science to figure some of this crap out.
