The line char.Head only seems to work for roblox default heads. How do I fix this to work for all heads? 

--Variables
local rep = game:GetService("ReplicatedStorage") --You can change this to ServerStorage for more security.
local nametag = rep.NameTag 
local r = 255
local g = 0
local b = 0

--Functions
game.Players.PlayerAdded:Connect(function(player)
	player.CharacterAdded:Connect(function(char)
		--Varibles
		local head = char.Head
		local newtext = nametag:Clone() --Cloning the text.
		local uppertext = newtext.UpperText
		local lowertext = newtext.LowerText
		local humanoid = char.Humanoid
		
		humanoid.DisplayDistanceType = "None"
		
		--Main Text default
		newtext.Parent = humanoid
		newtext.Adornee = humanoid
		uppertext.Text = player.Name --Changes the text to the player's name.
