Well, can you tell us which line the error is coming from?

it has something to do with the picked winner inside the table, right here;

			if #PlayersInGame >= 2 then
				for i = Settings.TimeBetweenEvents, 1, -1 do
					Status.Value = "Next Event Is In "..i.. " Seconds!"
					wait(1)
				end
				if #PlayersInGame >= 2 then
					local Value = math.random(1, #PlayersInGame)
					local RandomPlayer = PlayersInGame[Value]

					Events(RandomPlayer)
					wait(2.5)
				else
					wait(5)
					for i, v in pairs(PlayersInGame) do
						table.remove(PlayersInGame, i)
					end
				end
			else
				Settings.RoundInProgress.Value = false
				if #PlayersInGame <= 1 then
					local Value = math.random(1, #PlayersInGame)
					local RandomPlayer = PlayersInGame[Value]
					if Value ~= nil then
						Status.Value = RandomPlayer.Name.." has won."
						for i, v in  pairs(game.Workspace.Folder:GetChildren()) do
							v:ClearAllChildren()
						end 
						wait(5)
						RandomPlayer.leaderstats.Wins.Value += 1
						RandomPlayer.leaderstats.Coins.Value += 12000
					end
				else
					Status.Value = "No one won!"
					wait(5)
				end
			end
		until Settings.RoundInProgress.Value == false
	else
		-- The game doesnt have enough players
		Status.Value = "Need more players to begin..."
	end
end```

are you there or are you currently out? (I’ll wait)

That error occurs when the minimum value is greater than the maximum value. Looking at the line you’re referring to I don’t see anything wrong with it.

The only thing I can think of is if #PlayersInGame is 0.

Where is the code that determines the amount of players in the game? It might be an issue with that.

But then how do i change it so that it actually picks the player before they get removed from the table?

7

I am unsure. I will play around with this code when I get the chance and get back to you

8

okay thanks but did you find anything out yet?

Replace if #PlayersInGame <= 1 then to if #PlayersInGame == 1 then
Because if #PlayersInGame is 0, this will fire and try math.random(1, 0), which will throw an error.

it still doesnt work as it just do not do the next even in 5 seconds it just pauses the script and completely pauses the game. the game does not end and the player is stuck on his own plate.
