Why the server couldn't find Players?

Why the server keeps saying this (2) when I already set the value(1)? (IT WORKS AT STUDIO, BUT NOT AT ROBLOX ;-;)

(1) ServerScriptService.LoadMapScript:9: attempt to index global 'LocalPlayer' (a nil value)

(2) "Players" setting script

Players = game:GetService("Players").LocalPlayer

Error script part

PlayerGui = Players.PlayerGui

Others: Whole script

wait(10)
print("LoadMapScript activated")
replicatedStorage = game:GetService("ReplicatedStorage")
serverstorage = game:GetService("ServerStorage")
Players = game:GetService("Players").LocalPlayer
win = game.ServerStorage.values:WaitForChild("win")
win.Value = 2
PlayerGui = Players.PlayerGui
GUIname = PlayerGui.MapName:WaitForChild("Name")
GUIcreator = PlayerGui.MapName:WaitForChild("Creator")
gamelocation = CFrame.new(math.random(51.5,58.5),2.5,math.random(128,136))
lobbylocation = CFrame.new(math.random(4065.5,4114.5),6.5,math.random(83.5,182.5))

function tptogame()
	if Players.Character and Players.Character:FindFirstChild("HumanoidRootPart") then
		Players.Character.HumanoidRootPart.CFrame = gamelocation
	end
end

function tptolobby()
	if Players.Character and Players.Character:FindFirstChild("HumanoidRootPart") then
		Players.Character.HumanoidRootPart.CFrame = lobbylocation
	end
end

function unloadMap()
	if workspace:FindFirstChild("Map") then
		workspace.Map:Destroy()
	end
end


function onPlayerAdded(player)
     print(player.Name .. " has entered the game")
end

--When a player joins, call the onPlayerAdded function
game.Players.PlayerAdded:connect(onPlayerAdded)

--Call onPlayerAdded for each player already in the game
for _,player in pairs(game.Players:GetPlayers()) do
     onPlayerAdded(player)
