First

function onClick()
	script.Parent.Parent.Parent.Parent.Parent.leaderstats.Deaths.Value = 0
	script.Parent.Parent.Parent.Parent.Parent.Character.Humanoid.Health = 0
	script.Players.LocalPlayer.TeamColor = BrickColor.new("Institutional white")
end

script.Parent.MouseButton1Click:connect(onClick)

Second

disabled = false

script.Parent.MouseButton1Click:connect(function()
	if disabled == false then
		disabled = true
		script.Parent.BackgroundColor3 = Color3.new(217, 0, 0)
		game.Workspace.Teleport.RemoteFunction:InvokeServer()
		wait(3)
		script.Parent.BackgroundColor3 = Color3.new(0, 154, 0)
		disabled = false
	end
end)

(i have to put the script into a textbutton)
