This part spawning script just doesnt work?

i am trying to make this part spawn a part when pressed ( with cooldown ), please explain why it doesnt work:

UserInputService = game:GetService("UserInputService")

local rannum = 1

local debounce = true

local cooldown = 0.5

UserInputService.InputBegan:Connect(function(key, typing)

if typing then return end 

local button = Enum.KeyCode.Delete

if key.KeyCode == button then

	if debounce then 

		debounce = false 

        if rannum == 1

	    then local poopspawned = 0

        while true do

				if poopspawned >= 1 then

					wait()

			poopspawned = poopspawned + 1

			local poop = Instance.new("Part", game.Workspace)

			time()

			poop.Color = Color3.new(0,0,0)

			poop.Position = Vector3.new(0,15,0)

		end

		wait(2) 

				debounce = true

			end

		end

	end

end

end)
