I am scheduling tennis matches. Each match consists of 2 lines of singles and 3 lines of doubles. For each match I have 12 players to select from for 10 spots. I am using a combo box to select the players for each position. How can I preclude the selection of the same player twice? In other words, once a player has been selected and he/she is chosen again, I would like to see a message saying the player was already selected and give me the opportunity to override or not.
Thanks....
