Why does this not give me a cup?

So when you click a part Inside the model 'Cup' (which is inside the model, Medium) its supposed to give you a cup, but for some reason its not

for i, part in pairs(workspace.Medium.Cup:GetChildren()) do
	print("cup loaded")
	if part:IsA("Part") then
		mouse.Button1Down:connect(function()
			print("click")
		    local targ = mouse.Target
		    if targ == part then
				print("target")
				game.Lighting.Medium.Cup:Clone().Parent = plr.Backpack
				print("gave")
			end
		end)
	end
end

EDIT: it doesnt print anything

FULL:

plr = game.Players.LocalPlayer
mouse = plr:GetMouse()

for i, model in pairs(workspace.Pizza:GetChildren()) do
	mouse.Button1Down:connect(function()
	    local targ = mouse.Target
	    if targ == model then
			game.Lighting.Pizza:Clone().Parent = plr.Backpack
		end
	end)
end

for i, model in pairs(workspace.Sandwiches:GetChildren()) do

	end)
end
