I need help with a script I've been making for my game, as it is not working. Could anybody help?

local button = script.Parent
local Gui = script.Parent.Parent.Parent.Parent.Parent.Parent
local Gui = script.Parent.Parent

button.MouseButton1Up:Connect(function()
	script.Parent.Parent.Visible = false
	game.Workspace.boo.Playing = true
	game.Workspace.boo.TimePosition = 0
	script.Parent.Parent.Parent.Parent.Parent.Parent.BOO.ImageLabel.ImageTransparency = 0
	wait(5)
	script.Parent.Parent.Parent.Parent.Parent.Parent.BOO.ImageLabel.ImageTransparency = 1
end)

Hello! My name is Ethan, I am starting out on developing on ROBLOX. I was making some code for my game, which is supposed to jumpscare people once pressed. For some reason, the jumpscare image doesn't appear for the whole server, only the person who pressed it. I would like some help as I tried many things to fix this problem. There are images that can help you here

1. LocalScript inside Button ==================

-- Define Gui stuff
local Button = script.Parent  -- Grab button...
local BooLabel = button.Parent.Parent.Parent.Parent.Parent.BOO.ImageLabel -- ... and label

-- Define Workspace stuff
local Boo = workspace.boo

-- Define Event stuff
local RS = game:GetService("ReplicatedStorage") 
local JumpscareEvent = RS:WaitForChild("JumpscareEvent") -- Grab both items
local JumpscareClient = RS:WaitForChild("JumpscareClient")

-- Define Player stuff
local Players = game:GetService("Players") 
local LocalPlayer = Players.LocalPlayer -- Grab local player

-- Define other Variables 
local Debounce = false -- Debounce to prevent button spamming

-- Connect button
Button.Activated:Connect(function() -- When button is clicked or tapped 
	if not Debounce then -- Detect if the button can be pressed
		Debounce = true -- Set debounce to true to stop further button presses
		JumpscareEvent:FireServer() -- Fires to server to tell other clients to jumpscare
		Button.Parent.Visible = false -- Make it invisible
		Boo:Play() -- Plays the sound
		BooLabel.Visible = true -- Make it visible
		wait(5) -- Wait
		BooLabel.Visible = false -- Make it invisible
		Debounce = false -- Set it to false so we can press it again
	end
end)

-- Connect event
JumpscareClient.OnClientEvent:Connect(function(Player) -- Waits for event 
	if Player ~= LocalPlayer then -- If the event wasn't fired by the client
		Boo:Play() -- Plays the sound
		BooLabel.Visible = true -- Make it visible
		wait(5) -- Wait
		BooLabel.Visible = false -- Make it invisible
	end
end)

1. Create events ======================

In replicated storage, add two RemoteEvents, one called JumpscareEvent, one called JumpscareClient

1. Server Script ======================

Put this script in ServerScriptStorage

-- Define Event stuff
local RS = game:GetService("ReplicatedStorage") -- Grab Both events
local JumpscareEvent = RS:WaitForChild("JumpscareEvent")
local JumpscareClient = RS:WaitForChild("JumpscareClient")

JumpscareEvent.OnServerEvent:Connect(function(Player) -- Waits for event
	JumpscareClient:FireAllClients(Player) -- Fires it back out again
end)
