I am trying to make a hide and seek game. I am trying to make it so when the seeker leaves the game or gets disconnected, then the round is over and the contestants is 0. But for some reason when I add the hashtag its underlined red. Here is the code:

-- Services
local replicatedStorage = game:GetService("ReplicatedStorage")
local serverStorage = game:GetService("ServerStorage")

local status = game.ReplicatedStorage.Values.Status

local timer = replicatedStorage.Values.Timer

local playersLeft = replicatedStorage.Values.PlayersLeft

local hitbox = serverStorage:WaitForChild("Hitbox")
--Config
local playersToStart = 2

local contestants = {}

--Functions

local function chooseSeeker(availablePlayers)
	return availablePlayers[math.random(1, #availablePlayers)]
end

local function teleportPlayers(availablePlayers,spawns) -- availablePlayers: Table / spawns: Table
	for _, plr in pairs(availablePlayers) do
		if plr.Character then
			if plr.Character:FindFirstChild("HumanoidRootPart") then
				plr.Character.HumanoidRootPart.CFrame = spawns[math.random(1, #spawns)].CFrame + Vector3.new(0,5,0)
	        end
		end
	end
end

local function toMS(s)
	return ("i:i"):format(s/60%60, s%60)
end

local function addHitbox(player)
	
	if player then
	    if player.Character then
			local character = player.Character
			local hitboxClone = hitbox:Clone()
			hitboxClone.CFrame = character.HumanoidRootPart.CFrame
			local weld = Instance.new("Weld")
			weld.Part1 = character.HumanoidRootPart
			weld.Part0 = hitboxClone
			weld.Parent = hitboxClone
			hitboxClone.Parent = character
			print("hitbox added for "..player.Name)
			
			return hitboxClone
		end	
	end
end

local function isContestant(plr)
	for _, contestant in pairs(contestants) do
		if contestant == plr then
			return true
		end
	end
	
	return false
end

local function kickOutContestant(plr)
	for i, contestant in pairs(contestants) do
		if contestant == plr then
			table.remove(contestants,i)
			print("Booted "..contestant.Name.."from the game")
		end
	end	
end

while wait(1) do
	
	contestants = {}
	
	repeat
		
		print("Not enough players in-game")
		status.Value = playersToStart.." players needed to start ("..#game.Players:GetPlayers().."/"..playersToStart..")"
		
		wait(1)
		
	until #game.Players:GetPlayers() >= playersToStart
	
	for i = 100,0,-1 do
		status.Value = "Next round starts in "..i.." seconds"
		wait(0.1)
	end
	
    contestants = game.Players:GetPlayers()
	
	local seeker = chooseSeeker(contestants)
	
	status.Value = "The chosen seeker is... "
	wait(1.5)
	status.Value = seeker.Name.."!"
	
	wait(3)
	
	local map = game.Workspace.TempMap
	
	kickOutContestant(seeker)
	
	teleportPlayers(contestants,map.Spawns:GetChildren())
	
	local hitbox = addHitbox(seeker)
	--disconnect me
	seekerHitboxConnection = hitbox.Touched:Connect(function(hit)
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player then -- real player
			print(player.Name)
			if isContestant(player) then
				print("Real contestant")
				kickOutContestant(player)
				status.Value = player.Name.." was killed by "..seeker.Name
				if player.Character then
					player.Character.Head:Destroy()
					wait(2)
				end
				print("Kicked")
			end
		end
	end)
	
	status.Value = "Get ready to hide!"
	
	wait(3)
	
	for i = 3,0,-1 do
		status.Value = "Go Hide! "..i.." seconds remaining"
		timer.Value = toMS(i)
		playersLeft.Value = #contestants
		wait(1)
	end
	
	teleportPlayers({seeker},map.SeekerSpawns:GetChildren())
	
	status.Value = "The Seeker Has Been Released!"
	
	seeker.PlayerGui.SpectateGui.Enabled = false
	
	if seeker.Character then
		seeker.Character.Humanoid.WalkSpeed = 30
	end
	
	wait(3)
	
	local outcome = nil
	
	for i = 100,0,-1 do
		status.Value = "Game in Progress! "..i.." seconds until next round."
		timer.Value = toMS(i)
		playersLeft.Value = #contestants

        function playerLeaving(player)
	        if player.Name == seeker.Name then
	            #contestants = 0
	            end
	        end
	    end
	 
	    game.Players.PlayerRemoving:Connect(playerLeaving)
		
		if #contestants == 0 then
			outcome = "SeekerWon"
			break
		end
			
		wait(1)
	end
	
	if outcome == "SeekerWon" then
		status.Value = "The seeker has won the game!"
		seeker.leaderstats.Wins.Value = seeker.leaderstats.Wins.Value + 1
		seeker.leaderstats.Coins.Value = seeker.leaderstats.Coins.Value + 70
	else
		status.Value = "Time's up everybody! The contestants have won!"
		for i, contestant in pairs(contestants) do
			contestant.leaderstats.Wins.Value = contestant.leaderstats.Wins.Value + 1
			contestant.leaderstats.Coins.Value = contestant.leaderstats.Coins.Value + 50
		end
	end
	
	seeker.Character.Humanoid.Health = 0
	for i, contestant in pairs(contestants) do
		contestant.Character.Humanoid.Health = 0
	end
	wait(5)
	
	status.Value = "End of Round"

	if seekerHitboxConnection then seekerHitboxConnection:Disconnect() print("Successfully disconnected") end
	
	wait(2)
end

But through lines 158-165, on line 160, the # in #contestants is underlined red. I need help please
