here is the local script

player = script.Parent.Parent
char = player.Character

levelValue = script.Parent.ExperienceGui.Background.Background.level
Head = char:WaitForChild("Head")
bill = char.Head:WaitForChild'BillboardGui'
bill.Frame.LevelLabel.Text = ("Level".." "..levelValue.Value)

levelValue.Changed:connect(function(value)
	bill.Frame.LevelLabel.Text = ("Level".." "..levelValue.Value)
end)
