Pool League And Use To Track Player Handicaps

I run a small town pool league and use excell to track player handicaps, ect. we use a simple system for handicapping. Players can be from 2- to 7+ (2- 2 2+ 3- 3 3+ 4- 4 4+) and so on. if a player is a 2+ and wins they go to a 3- and so on. I want to be able to just type a W or an L and have it look up the players previous handicap and return a new handicap in the next field. I've allready figured out how to count the W's and L's and return the total for a teams weekly wins on another page, and give stats on a players wins and losses. I then print each sheet out weekly. Teams have 8 players but only play 5 each week so some players might not play for 2,3 or more weeks. I also use access to keep track of all the people that have played in the league. some players play a few sessions then quit for a few. this way i can keep track of their handicaps when not playing and havew a list of all the people that have played in the league. Can i get excel to transfer a players handicap to access each time it changes?
