the script is this
function clicked() game.ServerStorage.WoodKey:Clone() game.ServerStorage.WoodKey = game.Players.Backpack end script.Parent.ClickDetector.MouseClick:Connect(clicked)
and there is no output im trying to clone one into the players backpack
You are cloning it and doing nothing with the clone first of all. Also, you are setting WoodKey (object) to Backpack, when you're trying to set its parent instead. Lastly, you're setting it to "Backpack" of the Players service, not the actual player.
Try this:
function clicked(Player) game.ServerStorage.WoodKey:Clone().Parent = Player.Backpack end script.Parent.ClickDetector.MouseClick:Connect(clicked)
