My print printes twice even tough there is a debounce it should only fire once else my script will kinda glitch

local Debounce = false

uis.InputBegan:Connect(function(input)
    if Debounce == false then
    if input.KeyCode == Enum.KeyCode.Space then
        Debounce = true
        print("Space bar pressed")
        local Screens = 1

        if Screens == 1 then
            script.Parent.Warn1.Visible = false
            script.Parent.Warn2.Visible = true
            Screens = 2
            warn(Screens)
            MakeUIAlive2()

        elseif Screens == 2 then
            script.Parent.Warn2.Visible = false
            script.Parent.HeadphonesNotice.Visible = true
            Screens = 3
            warn(Screens)
            MakeUIAlive3()

        elseif Screens == 3 then
            print("Ok?")
        end
