Whats wrong with my Billboard Gui Script? [Done]

I've been trying all day but the billboard doesn't show up how come??

clone = script.Parent.Parent.Head:clone()
clone.Parent = script.Parent.Parent.Head
clone.BrickColor = clone.Parent.BrickColor
clone.Name = "fake"
clone.Transparency = 0
clone.face:remove()
weld = Instance.new("Weld")
weld.Parent = script.Parent.Parent.Head
weld.Part0 = script.Parent.Parent.Head
weld.Part1 = clone
clone.CFrame = script.Parent.Parent.Head.CFrame
weld.C1 = CFrame.new(0, 0, 0) * CFrame.fromEulerAnglesXYZ(0,0,0)
user = game.Players:GetPlayerFromCharacter(script.Parent.Parent)
while true do  
script.Parent.Adornee = script.Parent.Parent.Parent.Head
script.Parent.talk.Text = script.Parent.Parent.Name .. ": " .. script.Parent.Parent.Humanoid.Health.."%"
if script.Parent.Parent.Humanoid.Health <= 30 then
		script.Parent.talk.TextColor3 = Color3.new(1,1,0) --red
	elseif script.Parent.Parent.Humanoid.Health <= 70 then
		script.Parent.talk.TextColor3 = Color3.new(1,0,0) --yellow
	elseif script.Parent.Parent.Humanoid.Health > 70 then
		script.Parent.talk.TextColor3 = Color3.new(0,1,0) --green
	elseif script.Parent.Parent.Humanoid.Health < 0 then
		script.Parent.talk.TextColor3 = Color3.new(0,0,0) --green			
	end
for i,v in pairs(game.Players:GetChildren()) do
if user.TeamColor == v.TeamColor then
script.Parent.talk.Visible = true
else script.Parent.talk.Visible = false end
wait(3)
end
end
