pivot table setup

Hey

I am trying to make a spreadsheet for the purpose of tracking how accurate a guess is for an nfl pick.

So what I have is a schedule, and will after each game mark a winner. If the guess was correct, I want to be able to assign each team playing 1 point if correct. If the guess was incorrect, I want it to subtract a point.

I want to be able to update this every week and have the total points tally up weekly, so I can see what teams are getting more correct guesses and what teams are getting wrong picks.

I hope this makes sense. I was thinking a pivot table would work, however it was only giving the points to one team, and I couldnt figure out how to do it for both.

Can anyone make a very simple version of this, you can just use team a, team b, etc, and I dont need scores.

When I tried, my categories were
away team, home team, winner, guessed winner, points

the home and away fields I have, the winner I have data up through the last game, guessed winner I have, and points was just a =if(guessed winner = winner,1,-1)

Thanks for any help!!
