Why is my script working in Roblox Studio but not in servers? (PLEASE HELP)

Dear Answerer,

I am making a game that has a game loop. The game loop works in Roblox Studio but does not work in normal playing on a server. The Game Loop (which is named Game Loop) was in Workspace. I then transferred it to ServerScriptService. And it still does not work. Any ideas on why? Script is placed below.

local winBoard = game.Workspace.Stationary.LobbyInternal.Jackel.SurfaceGui.TextLabel
local forest = game.ServerStorage.Maps["Forest Map"]
local plains = game.ServerStorage.Maps["The Great Plains"]
local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren()
local ChosenMap = Maps[math.random(1, #Maps)]



function Intermission()
			local IntermissionTime = 20
			wait(.1)
		while IntermissionTime ~= 0 do
			for _, player in pairs(game.Players:GetChildren()) do
			wait(.1)
		local playergui = player.PlayerGui
		local text = playergui.ScreenGui:WaitForChild('TextLabel')
				wait(.5)
				text.Text = "Intermission: " .. IntermissionTime
				wait(.3)
				IntermissionTime = IntermissionTime - 1
			end
		end
	
	
	
end


function HideTimer()
			local HideTime = 20
			wait(.1)

			for _, player in pairs(game.Players:GetChildren()) do

		local playergui = player.PlayerGui
		local text = playergui.ScreenGui:WaitForChild('TextLabel')
				wait(.5)
				text.Text = "Time Left To Hide: " .. HideTime
				wait(.3)
				HideTime = HideTime - 1
			end
		end
