How do i make Remote Functions Arguments work??

the error is 'BackgroundTransparency is not a valid member of Player 22:56:19.535 - Stack Begin'

local oo= Instance.new("RemoteEvent")
oo.Name = "CharChangeEvent"
oo.Parent = game.ReplicatedStorage.RemoteEvents.Gui
oo.OnServerEvent:connect(function(Player, X)

		end
	end
end)

Called

FaceButt.MouseEnter:connect(function()
	game.ReplicatedStorage.RemoteEvents.Gui.CharChangeEvent:FireServer(Player,FaceButt)
end)

It says the property isnt in player but Its supposed to be in The button?
