plr = game.Players.LocalPlayer
Cash = plr:WaitForChild("stats").Cash
XP = plr.stats.XP

script.Parent.Humanoid.Died:connect(function()
	wait(1)
    model:remove()
	Cash.Value = Cash.Value +30
	XP.Value = XP.Value +10
    model = backup:Clone()

Is it a script? If so you can't get the local player through script
