Need help!

I come to you programmers in desperation.  I'm by no means a programmer and have never claimed to be.  I'm using visual c# to create a scoreboard for a business I work for that will be displayed on a large tv in the room.  Problem I have is I have rows of Numerical up/down boxes, and I need them to total at the bottom, so that you can see the running total scores for each team.  Is there a way to do this without getting my typing fingers dirty or do I need to gb2 for dummies?  Please help!

if box1 == 2 && box2 == 4 && box3 == 2
  result = 8

Repeat for as many combinations as you think are needed.  Don't go overboard, they probably won't increase the counters too high.
