[SOLVED] Tutorial gui doesn't get parented to the playerGui?

Hello. I'm trying to make a tutorial for my game, and when I try to test it, it won't get parented to the playergui.

-- Portion of the script
if levels.Value == 1 then
	print("Start tutorial") -- it prints
	game.ReplicatedStorage.Remotes.StartTutorial:FireClient(player)
end

-- Client

local player = game.Players.LocalPlayer
local playerGui = player:WaitForChild("PlayerGui")
local tutorial = game.ReplicatedStorage.Tutorial

local runService = game:GetService("RunService")

game.ReplicatedStorage.Remotes.StartTutorial.OnClientEvent:Connect(function(player)
	tutorial.Parent = playerGui -- this would be the problem I suppose
end)

if tutorial.Parent == playerGui then
	for i = 1, #start do
		script.Parent.TextLabel.Text = string.sub(start, 1, i)
		runService.RenderStepped:Wait()
	end
	
	script.Parent.Parent.Skip.Visible = false
	wait(1.5)
				
	for i = 1, #messages[1] do
		script.Parent.TextLabel.Text = string.sub(messages[1], 1, i)
		runService.RenderStepped:Wait()
	end
	
	wait(1.5)		
	
	for i = 1, #messages[2] do
		script.Parent.TextLabel.Text = string.sub(messages[2], 1, i)
		runService.RenderStepped:Wait()		
	end
	
	wait(1.5)
	script.Parent.Parent.Arrow:TweenPosition(UDim2.new(0.28, 0, 0.63, 0), "Out", "Linear", 1)
	
	for i = 1, #messages[3] do
		script.Parent.TextLabel.Text = string.sub(messages[3], 1, i)
		runService.RenderStepped:Wait()		
	end
	
	script.Parent.Parent.Arrow.Position = UDim2.new(2, 0, 2, 0)
	wait(1.5)
	script.Parent.Parent.Arrow:TweenPosition(UDim2.new(0.28, 0, 0.58, 0), "Out", "Linear", 1)
	
	for i = 1, #messages[4] do
		script.Parent.TextLabel.Text = string.sub(messages[4], 1, i)
		runService.RenderStepped:Wait()
	end
	
	script.Parent.Parent.Arrow.Position = UDim2.new(2, 0, 2, 0)
	wait(1.5)
	script.Parent.Parent.Arrow:TweenPosition(UDim2.new(0.28, 0, 0.66, 0), "Out", "Linear", 1)
	
	for i = 1, #messages[5] do
		script.Parent.TextLabel.Text = string.sub(messages[5], 1, i)
		runService.RenderStepped:Wait()
	end
	
	script.Parent.Parent.Arrow.Position = UDim2.new(2, 0, 2, 0)
	wait(1.5)
	script.Parent.Parent.Arrow:TweenPosition(UDim2.new(0.67, 0, 0.84, 0), "Out", "Linear", 1)
	
	for i = 1, #messages[6] do
		script.Parent.TextLabel.Text = string.sub(messages[6], 1, i)
		runService.RenderStepped:Wait()
	end
	
	script.Parent.Parent.Arrow.Position = UDim2.new(2, 0, 2, 0)
	wait(1.5)
	
	for i = 1, #messages[7] do -- end of tutorial
		script.Parent.TextLabel.Text = string.sub(messages[7], 1, i)
		runService.RenderStepped:Wait()
	end

	wait(0.5)
	tutorial.Parent = game.ReplicatedStorage
end
