This is what my data is:
B= BLIND SCORE TOTALS
GM1 GM2 GM3 GM4 GM1 GM2 GM3 GM4 SERIES BOWLED # OF GAMES
D E F G H I J K M
O
B B 0 0 100 100 150 150 300
2

D THRU G WILL EITHER = "B" OR "0"
H THRU K WILL EITHER = 0 OR 0
I NEED "M" TO ONLY TOTAL VALUE OF "H" THRU "K" ONLY WHEN "D" THRU "G" = 0
I NEED "O" TO ONLY BE +1 EACH TIME "H" THRU "K" 0 & "D" THRU "G" = 0

I know what I want but, not even sure if I am explaining it correctly.
PLEASE HELP ME.
Thanks,
Pat
