BillBoard GUI Not showing for everyone?

wait(1)
local player = game.Players.LocalPlayer
print("Found Player")
local character = player.Character
print("Found character")
local Health = player.Character.Humanoid.Health
print("Found health")
local MaxHealth = player.Character.Humanoid.MaxHealth
print("Found MaxHealth")


local bg = Instance.new("BillboardGui")
bg.Parent = player.PlayerGui
bg.Adornee = character.Head
bg.Size = UDim2.new(1, 0, 1, 0)
bg.StudsOffset = Vector3.new(0, 2, 0)
print("MadeGui") 

local frame = Instance.new("Frame")
frame.Parent = bg
frame.Size = UDim2.new(1, 0, 1, 0)
frame.BackgroundTransparency = 1
frame.BackgroundColor3 = Color3.new(1, 1, 1)
print("Made Frame")

local text = Instance.new("TextLabel")
text.Parent = frame
text.Position = UDim2.new(0.25, 0, 0.25, 0)
text.Size = UDim2.new(0, 150, 0, 20)
text.BorderSizePixel = 0
text.TextScaled = true
text.TextWrapped = true
text.Text = Health.."/"..MaxHealth
print("Made Text")

player.Character.Humanoid.Health.changed:connect(function(HTH)
    text.Text = Health.."/"..MaxHealth
    print(player.name .. Health.."/"..MaxHealth)
end)

Also at line 36, It is getting an error for 'Health' Is it because of the local Health? Probs.... But anyways.. I was wondering if there was something that I needed to do to the BillBoard GUI to make it so everyone can see it.

Edit: I was just reading up on some stuff.. And the way that it did it was that it created a new brick, then put that BillBoard GUI attacked to the brick and put it inside the players head. Is there any other way to do this then doing that?
