Pull specific values from array to calculate - php

Question

I have 2 tables. Table 1 is a schedule which holds weekly games. Table 2 is a separate table where you select just one team from the scheduled games for a week.
I am trying to get the difference in the score for the game that I chose a team for. So for a specific week, there are 13-16 games. I select 1 team from one of those games. If the team I pick wins, the result is the difference in the score. So if my team wins and the score is 27-10, I show 17 point. I have tried every way I can think to get this, but the best I seem to come up with is that it will calculate the last game of the week only, not the specific game that my team is involved in. The gameID is the key between both tables. Is it possible to do this? I thought by grabbing the values based on gameID from the array it would match it to the gameID associated with the selection from table 2.I am able to display the correct team, week by week, but not get the point differential for that specific game. Any ideas?
