My script doesnt work correctly when my player spawn?

For the module script: Make a string value in Replicated Storage and name it "Status". Put the module script in ServerScriptService

local module = {}
		
	module.Intermission = function(length)
		local Status = game:GetService("ReplicatedStorage"):WaitForChild("Status")
		
		for i = length, 0, -1 do 
			
			Status.Value = "Intermission: "..i.." seconds left"
			
			wait(1)
			
		end
	end
	
	
	module.Round = function(length)
		local Status = game:GetService("ReplicatedStorage"):WaitForChild("Status")	
		
		for i = length, 0, -1 do
			
			Status.Value = "Round in Progress: "..i.." seconds left"
			
			wait(1)
			
		end
	end
return module







--Server Script


local RoundModule = require(script.Parent.Module)


while true do
	
	RoundModule.Intermission(30) --This is the amount of time you want your intermission to be
	wait()
	RoundModule.Round(150) --This is the amount of time you want your Round to be.
	
end



--Now insert a ScreenGUI in StarterGUI and insert a TextLabel and customize it however you want. Name the TextLabel "RoundGUI". Insert a local script in the ScreenGUI.

--Local script


local Status = game:GetService("ReplicatedStorage"):WaitForChild("Status")

local RoundGUI = script.Parent:WaitForChild("RoundGUI")


Status:GetPropertyChangedSignal("Value"):Connect(function()

	RoundGUI.Text = Status.Value

end

And that is all!

Remember you can always edit the script to add more text for your round that suits your game.
