[Solved]Why is my round system template not working? What am I doing wrong?

I was just making a round system for a template, but something is very wrong.

Client:

local StarterGui = game:GetService("StarterGui")
local RoundGui = StarterGui:WaitForChild("RoundGui")
local Timer = RoundGui:WaitForChild("Timer")
local RoundInfo = RoundGui:WaitForChild("RoundInfo")

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Remotes = ReplicatedStorage:WaitForChild("Remotes")
local StartTimerEvent = Remotes:WaitForChild("StartTimer")

function StartTimer(eventName, timeToCount)
	print("ClientWorking")
	RoundInfo.Text = eventName
	for i = timeToCount, 0, -1 do
		--OldScript: print("ForLoopWorking")
		print("ForLoopWorking: "..i) --NewScript 
		wait(1)
		Timer.Text = tostring(i)
	end
end

StartTimerEvent.OnClientEvent:Connect(StartTimer)

Server:

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local Remotes = ReplicatedStorage:WaitForChild("Remotes")
local StartTimerEvent = Remotes:WaitForChild("StartTimer")

local Configuration = script:WaitForChild("Config")
local Enabled = Configuration:WaitForChild("Enabled").Value
local IntermissionTime = Configuration:WaitForChild("IntermissionTime").Value
local RoundTime = Configuration:WaitForChild("RoundTime").Value

function StartRound()
	StartTimerEvent:FireAllClients("Intermission", IntermissionTime)
	wait(IntermissionTime)
	StartTimerEvent:FireAllClients("Round", RoundTime)
	wait(RoundTime)
end

if Enabled then
	wait(8)
	print("ServerWorking")
	StartRound()
end

Everything printed, The remotes fired, but none of the gui changed text, and I can't figure out what is making it fail.

My resources are all in their respective folders and my configs are set to valid values. Edit: What is even stranger is that the timer actually counts down if I add "i" to the print values.

It turns out it was a loading error. I just manually set the UI at the beginning under playergui instead, and it worked, so the issue is resolved.
