Trash Can Script Not Working?

It is supposed to remove a empty cup from somones inventory and move it on top of a tray. Can you help me fix?

local mugs = script.Parent.Parent.Mugs
local M1,M2,M3,M4,M5,M6,M7,M8 = mugs.M1,mugs.M2,mugs.M3,mugs.M4,mugs.M5,mugs.M6,mugs.M7,mugs.M8
local enabled = true
local create = Instance.new

function RandPart(obj1)
	local parts = {}
	for _,v in pairs(obj1:GetChildren()) do
		table.insert(parts, v)
	end
	return parts[math.random(1,#parts)]
end

script.Parent.ClickDetector.MouseClick:connect(function(player)
	if player:GetRankInGroup(1107003) == 0 then
		if script.Parent.Parent.Mugs.M8.Transparency == 0 then
			MugsInvis()
			y = player.Backpack
			z = game.Lighting.Tray
			z:Clone().Parent = y
			player.Character.Humanoid:EquipTool(z)	
		end
	end
end)

script.Parent.Touched:connect(function(h)
	if h.Parent ~= nil and h.Parent.Name == "Mug" and h.Parent.Trash.Value == true then
		if enabled then
			enabled = false
			if M1.Transparency == 1 then
				M1.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M2.Transparency == 1 then
				M2.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M3.Transparency == 1 then
				M3.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M4.Transparency == 1 then
				M4.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M5.Transparency == 1 then
				M5.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M6.Transparency == 1 then
				M6.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M7.Transparency == 1 then
				M7.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			elseif M8.Transparency == 1 then
				M8.Transparency = 0
				enabled = true
				h.Parent:Destroy()
			else
				local h = create("Hint", Workspace)
				h.Text = "Employee needed to wash mugs"
				wait(4)
				h:Destroy()
				enabled = true
			end
		end
	end
end)

function MugsInvis()
	for _,v in pairs(script.Parent.Parent.Mugs:GetChildren()) do
		if v:IsA("BasePart") then
			v.Transparency = 0
		end
	end
end

I don't know if it's my computer not loading properly or if you havnt put your code within the LUA block... If you havnt, in future click the blue circle with "LUA" inside and put your code in that, makes it easier to read... Until you've done that, in not even going to begin to read it...
