function module.PointScore_Tier1()

        local players = game.Players.LocalPlayer
        local random = math.random(1,900)               ---X Axis random generator DO 
        local xnew = random/1000
        game.StarterGui.RandomXP.PopUp1.Position = UDim2.new(xnew, 0,1,0)
        game.StarterGui.RandomXP.PopUp1.Text = math.random(1,2000)                  
        game.StarterGui.RandomXP.PopUp1.TextColor3 = Color3.new(1, 0, 0)            
        game.StarterGui.RandomXP.PopUp1.Font = Enum.Font.Cartoon                            print("fully works")
        local PopUp1 = game.StarterGui.RandomXP.PopUp1
