checkers game help

hi was looking over some of my old work from when i very first started using blender, and i stumbled across my checkers board.

i’v been trying to crrate it into a game but i am having troubles. all iv got is a selector that moves around the board via an ipo. i need a way to have two selectors come up when i press a certain button, can i do this with logic bricks or am i going to have to learn to use python (which id prefer not to, iv already trying but it doesnt work for me)

plz help me. here is the blend file in case anybody wants it.

thanx in advance
