Number sequence error when I try to make the Particle emitter go invis?

Somethings wrong with my script, I don't know..

local UserInputService = game:GetService("UserInputService")
local plr = game.Players.LocalPlayer
local char = plr.Character or plr.CharacterAdded:Wait()
local charname = char.Name


if plr.Team == game.Teams.ISD then
	UserInputService.InputBegan:Connect(function(input)
	if input.KeyCode == Enum.KeyCode.E then
		local cloneSmoke = game.Lighting.Smoke:Clone()
		cloneSmoke.Parent = char.UpperTorso
		wait(1)
		char.UpperTorso.Smoke.Transparency = 1
		
	end
end)
end

It is giving me the error...
