I am unable to make my GUI slowly fade away. What script will make the GUI fade away?

local debounce = false

local userinputservice = game:GetService("UserInputService")

userinputservice.InputBegan:Connect(function(input, gameProcessedEvent)

    if not debounce then

        debounce = true

    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.1
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.2
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.3
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.4
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.5
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.6
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.7
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.8
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 0.9
    wait(1)
    script.Parent.ScreenGui.Frame.BackgroundTransparency = 1
        wait(1)

        wait(10)

        debounce = false

        end

    end)
