I have a question, maybe someone can tell me how to set a limit, for example, if someone upgrades a weapon, that he can only use this upgrade if the server has 20 players. But when Server have 19 Players the upgrade get auto disabled. Is that even possible?

Could someone show me this with the help of this example sma?
