My debounce is not working with a "Touched function", what is wrong? (SOLVED)

Hey, This script works fine, the only thing that does not work is the debounce, what is wrong?

The "dead" part should damage the player after the part have blinked and then just be a normal part again after 5 sec. But now it damage the player all the time, help.

while true do
wait(5)
debounce = false

script.Parent.Transparency = 1
wait(1)
script.Parent.Transparency = 0
wait(1)
script.Parent.Transparency = 1
wait(1)
script.Parent.Transparency = 0
wait(1)

debounce = true

if debounce == true then

script.Parent.Touched:Connect(function(hit)
				
				local humanoid = hit.parent:FindFirstChild("Humanoid")
				if humanoid then
				humanoid.Health = humanoid.Health -1
				end
				
			end)
			end

end

Thanks!

Try to define the debounce outside the function so

local debounce = false -- or true

while true do
wait(5)
debounce = false

script.Parent.Transparency = 1
wait(1)
script.Parent.Transparency = 0
wait(1)
script.Parent.Transparency = 1
wait(1)
script.Parent.Transparency = 0
wait(1)

debounce = true

if debounce == true then

script.Parent.Touched:Connect(function(hit)

                	local humanoid = hit.parent:FindFirstChild("Humanoid")
                	if humanoid then
                		humanoid.Health = humanoid.Health -1
                	end

            	end)
            end

	end
end
