Why isn't this remote event not firing?

I'm trying to use a remote event to make a GUI appear on the screen of somebody who touches a button on the floor and then for it to be removed after a couple of seconds. The remote event itself can be found in ReplicatedStorage along with the receiving Script. None of the Scripts used are Localscripts as when I change the script inside of the button to a Localscript, absolutely nothing will happen - it doesn't even print the user you touched the button.

All help is appreciated.

-- Script inside the block to touch

local part = script.Parent
local debounce = false
local ReplicatedStorage = game:GetService("ReplicatedStorage")

part.Touched:Connect(function(hit)
    if debounce == true then return end
    debounce = true
	print(hit.Parent.Name .. " has touched a part!")
	local Player = game.Players:GetPlayerFromCharacter(hit.Parent)
	game.ReplicatedStorage.ShowGui:FireClient(Player)
	
	if Player and not Player.PlayerGui:FindFirstChild(Gui.Name) then
		Player.PlayerGui.MessageGui.Message.Alert.Text = "You Touched Me!"
	end		
    wait(5)
	Player.PlayerGui.MessageGui:Destroy()
    debounce = false
		end)

-- Script inside ReplicatedStorage

local player = game.Players.LocalPlayer
local Gui = game.ReplicatedStorage.MessageGui

game.ReplicatedStorage.ShowGui.OnClientEvent:connect(function(player)
	Gui:Clone().Parent = player.PlayerGui
	wait(3)
	player.PlayerGui.MessageGui:Destroy()
end)
