I have been trying to do an offensive substitution of the batter by clicking on the batter. A screen appears with a list of players but the players shown on the list are the current roster. I don't want to change the positions of any of the current players. I want to substitute a player on the bench. How do I get a list of other players so that I can choose one to substitute?

If you are not seeing Offensive substitutions when tapping the batter, it means you have all players set to Batting = YES (so nobody is available on the bench to put in their spot). Please see this section of the iScore documentation:
