Yeah, the counter only goes up to 5 each since it's exceedingly rare for either team to score more than 5 points in a given game (any time I've played they've only hit up to 4 at max.) It shouldn't crash the whole ppt though. The box will disappear when you click the 5, however.

(On the odd chance that they do score 6 or above, I'm sure they'll all get a good chuckle like "holy crap, our score is off the charts/we broke the game." I used the same score board for my world cup soccer game and it got that response a few times.  )
