What is wrong with plrs?? why is it a "unknown global plrs" Here is my code.

-- Define Variables

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ServerStorage = game:GetService("ServerStorage")

local MapsFolder = ServerStorage:WaitForChild("Maps")

local Status = ReplicatedStorage:WaitForChild("Status")

local GameLength = 50

local reward = 250

-- Game Loop

while true do
	Status.Value = "Waiting for enough players"
	
	repeat wait(1) until game.Players.NumPlayers >= 2
	
	Status.Value = "Intermission"
	
	wait (10)
	
	
	local plrs = {}
	
	for i, player in pairs(game.Players:GetPlayers())do
		if player then
			table.insert(plrs,player)-- Add each player into plrs table
		end
	end
	
	wait(2)
	
	local AvilableMaps = MapsFolder:GetChildren()
	
	local ChosenMap = AvilableMaps[math.random(1,#AvilableMaps)]
	
	Status.Value = ChosenMap.Name.." Chosen"
	
	local ClonedMap = ChosenMap:Clone()
	ClonedMap.Parent = game.Workspace
	
	-- Teleport Players To The MAP
	
	local SpawnPoints = ClonedMap:FindFirstChild("SpawnPoints")
	
	if not SpawnPoints then
		print "Spawnpoints not found my dude FIX IT"
	end
	
	local AvailableSpawnPoints = SpawnPoints:GetChildren()
	
	for i, player in pairs(plrs) do
		if player then
			character = player.Character
			
			if character then
				-- Teleport them
				
				character:FindFirstChild("HumanoidRootPart").CFrame = AvailableSpawnPoints[1].CFrame
				table.remove(AvailableSpawnPoints,1)
				
				
				-- Give Them a Sword
				
				local Sword = ServerStorage.Sword:Clone()
				Sword.Parent = player.Backpack
				
				local GameTag = Instance.new("BoolValue")
				GameTag.Name = "GameTag"
				GameTag.Parent = player.Character
				
			else
				-- There is no character
				if not player then
					table.remove(plrs,i)
				end
			end
		end
	end
	
end
Status.Value = "Get ready to play!"

wait(2)

for i = GameLength,0,-1 do
	
	for x, player in pairs(plrs) do
		if player then
			
			character = player.Character
			
			if not character then
				-- left the game
			else 
				if character:FindFirstChild("GameTag")then
					-- They are still alive
					print(player.Name.."is still in the game!")
				else
					-- they are dead :C
					table.remove(plrs,x)
					print(player.Name.."Has been removed!")
				end
			end
		else
			table.remove(plrs,x)
			print(player.Name.."Has been removed!")
		end
	end
	
	Status.Value = "There are "..i.." second remaining, and"..#plrs.." players left"
	
	
	if #plrs == 1 then
		-- last person standing
		Status.Value = "The winner is "..plrs[1].Name
		plrs[1].leaderstats.Bucks.Value = plrs[1].leaderstats.Bucks.Value + reward
		break
	elseif #plrs == 0 then
		Status.Value = "OOOF Nobody Won!"
		break
	elseif i == 0 then
	  Status.Value = "Times Up!"
		break
	end
	
	wait(1)
end

print ("End of game")

for i, player in pairs(gamePlayers:GetPlayers()) do
	character = player.Character
	
	if not character then
