I'm making a tycoon, where more parts sold = higher water level; and the water is just a regular part that I want to move up depending on a leaderboard stat that can be contributed to by everyone. There is already a gui leaderboard with money kills and deaths listed for each player, so I am guessing that the value for water level is stored elsewhere but can still be added to by all 4 players. For example, one part (drop) increases the level by 0.01 studs. Also with the tycoon, how do I record how many parts have been sold in total by the player? This would make my solution easier.

Thank you
