using debounce without the if then statement?

I have an if then statement, i want the script to work if someone has the gamepass and then it doesnt work if you dont have the gamepass, however the if then statment from the debounce and the else are messing up and combining

heres my script:

local PassId = 4835177
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local MarketplaceService = game:GetService("MarketplaceService")
local BloxyCola = ReplicatedStorage:WaitForChild("????? ???? ???")
local player = game.Players.LocalPlayer
local bloxy = workspace:WaitForChild("itemgiver1")
local debounce = false

bloxy.ClickDetector.MouseClick:Connect(function(player)
         if MarketplaceService:UserOwnsGamePassAsync(player.UserId, PassId) then --if they have the gamepass
        if not debounce then

        debounce = true 

        BloxyCola:Clone().Parent = player.Backpack
        bloxy.ClickDetector.MaxActivationDistance=0
        bloxy.Transparency=1
        for i = 60, 1, -1 do -- give it a 60 second cooldown and show the timer
            bloxy.BillboardGui.TextBox.Text = tostring(i)
            wait(1)
        end

        bloxy.ClickDetector.MaxActivationDistance=10
        bloxy.BillboardGui.TextBox.Text=(" ") --replaces text and resets everything back to normal
        bloxy.Transparency = 0

        debounce = false -- allow the script to be run again
        else
 MarketplaceService:PromptProductPurchase(player.Bloxy, PassId)



end
    end
end)

is there anyway to make it where the script can be disabled without debounce or that debounce doesnt have an if then statment?
