I do league schedules and I need to check them for home and away and how many games. I want to be able to check a range from A4 to D18 and total up the 1- and then the -1 and do this for all 8 teams. How can I do this?

1-2 3-4 5-6 7-8
1-3 2-4 5-7 6-8
4-1 2-5 3-7 8-6



teams -1 1- -2 2- -3 3-
totals 1 2 1 2 1 2
