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
