If for some reason you want to re-copy indexes \ handicaps from the Membership Roster to the tournament you are viewing, pull down the Tools menu and click Update handicaps from roster.  Type YES to update the handicaps.

It is important to note that when you sign up a player in a tournament, TM copies the handicap and other tournament defaults he\she has in the membership roster at that moment in time to the tournament. This feature allows one player to have a different handicap, flight, tee group, etc in any number of tournaments. It also means that if you go to the membership roster and change the player's Tournament Defaults, it will not automatically change for each tournament they are signed up in. To change the handicap, flight, tee group, etc for a player in a specific tournament, go to the Sign Up Sheet (right side) or Tournament Sheet of that tournament and change the player's information there.
