The way you are doing it looks tricky. Lots of maybe this, maybe that, what if this but not that.
Instead would it be easier to simply send both scores in the MultiCast and set both progress bars where progress bar A percent = Team A score divided by max score, progress bar B = Team B score divided by max score?
Max Score in your situation seems like it would be the total of both teams scores, ie Team A score + Team B Score. like a kind of zero-sum game.
You can do it your way too but It looks like the branching logic is telling it to only set team B based on Team A logic.
