Figure golf bets using C#

Question

Would like to figure golf bets with variable number of players week to week.
Handicaps change every two weeks.
I have the "net score for each hole" algorithm complete for taking the gross score and computing if you get a stroke on that hole or not.
I am asking the program the following:
Player name: // not same players every week
Player handicap: // handicap changes every two weeks
Player gross score for all 18 holes: // hole1: hole2, etc.
I am successful up to this point for capturing info for 1 player and writing to array.
I would like to loop and capture the scores, figure bets, etc,. for all the players.
I keep leaning toward using arrays but get errors about using variable again.
I program as hobby and do not make my living doing programs.
Any tips or suggestion would be appreciated.
Here what have so far.
