I am making a minigame and it works smoothly in studio but in game it doesnt?

So I am making a minigame and I was just making it so the textlabel would say all the stuff like etc... I testing it many times in studio mode and it worked then i tested it in the actual game and it didn't work can anyone help me with this?

Repstore = game.ReplicatedStorage
maps = Repstore.Maps:GetChildren()

	while true do		
		if game.Players.NumPlayers > 1 then
		for i, v in pairs(game.Players:GetChildren()) do
			pgui = v:WaitForChild("PlayerGui")
			pgui:WaitForChild("MainText").TextLabel.Text = "Not enough players to start!"
		end
		else
			for i, v in pairs(game.Players:GetChildren()) do
			pgui1 = v:WaitForChild("PlayerGui")
			pgui1:WaitForChild("MainText").TextLabel.Text = "Chosing map"
			wait(3)
			ranGame = math.random(1, #maps)
			gameChosen = maps[ranGame]
			for i, v in pairs(game.Players:GetChildren()) do
			pgui2 = v:WaitForChild("PlayerGui")
			pgui2:WaitForChild("MainText").TextLabel.Text = "Map chosen: ".. gameChosen.Name
			wait(3)
			gameChosenClone = gameChosen:Clone()
			gameChosenClone.Parent = game.Workspace.MapSelected
			wait(3)
			spawns = gameChosenClone.Spawns:GetChildren()
			for i,v in pairs(game.Players:GetPlayers())do
				name = v.Name
				check = game.Workspace:FindFirstChild(name)
				if check then
					checkHumanoid = check:FindFirstChild("Humanoid")
					if checkHumanoid then
						check:MoveTo(spawns[i].Position)
					end
					end
					end
					end
			end
				for i, v in pairs(game.Players:GetChildren()) do
					for i = 3, 1, 1 do
			pgui3 = v:WaitForChild("PlayerGui")
			pgui3:WaitForChild("MainText").TextLabel.Text = "Game begins in".. i
				wait(1)
			end
			
				for i, v in pairs(game.Players:GetChildren()) do
					for i = 10,1, -1 do
			pgui4 = v:WaitForChild("PlayerGui")
			pgui4:WaitForChild("MainText").TextLabel.Text = "Time left ".. i
				wait(1)
				end
				end
			end
			for i, v in pairs(game.Players:GetChildren()) do
			pgui5 = v:WaitForChild("PlayerGui")
			pgui5:WaitForChild("MainText").TextLabel.Text = "Game ended"
			wait(3)
			gameChosenClone:Destroy()
			
			for i, v in pairs(game.Players:GetChildren()) do
				for i = 60,1,-1 do
			pgui6 = v:WaitForChild("PlayerGui")
			pgui6:WaitForChild("MainText").TextLabel.Text = "Intermission ".. i
			
			end
			end
			end	
			end
		wait(1)

Hey there, there are a few errors with your code.

Client-Server Replication

With FilteringEnabled now being a mandatory thing, client to server replication is more important then ever. Server Scripts cannot access a player's PlayerGui, and Local Scripts cannot access certain services such as ServerStorage and ServerScriptService. You'll have to use RemoteEvents and RemoteFunctions to get around this and other restrictions.

Hints

The Hint object has been deprecated in favor of TextLabels. You should not use a Hint, rather use a TextLabel at the top of the screen.

A little side-note:

• It is not recommended to use the 2nd argument of Instance.new. You should instead set it's parent via .Parent = X.

• It's good practice to change your variables into local variables.
