Anybody know why the debounce in this script isnt working?

local debounce = true
local cooldown = 3
local Sound = script.Parent.Parent.Parent.taw.Sound
local Light = script.Parent.Parent.Parent.taw.Light
local Particle1 = script.Parent.Parent.Parent.taw.Particle1
local Particle2 = script.Parent.Parent.Parent.taw.Particle2
local ParticleEmitter1 = script.Parent.Parent.Parent.taw.ParticleEmitter1
local ParticleEmitter2 = script.Parent.Parent.Parent.taw.ParticleEmitter2
local ParticleEmitter3 = script.Parent.Parent.Parent.taw.ParticleEmitter3
local ParticleEmitter4 = script.Parent.Parent.Parent.taw.ParticleEmitter4
local ParticleEmitter5 = script.Parent.Parent.Parent.taw.ParticleEmitter5
local ParticleEmitter6 = script.Parent.Parent.Parent.taw.ParticleEmitter6
local ParticleEmitter7 = script.Parent.Parent.Parent.taw.ParticleEmitter7
local ParticleEmitter8 = script.Parent.Parent.Parent.taw.ParticleEmitter8
local ParticleEmitter9 = script.Parent.Parent.Parent.taw.ParticleEmitter9
local ParticleEmitter10 = script.Parent.Parent.Parent.taw.ParticleEmitter10

script.Parent.MouseClick:Connect(function()
	if debounce then
		debounce = false
	end
	Sound:Play()
	Light.Enabled = true
	Particle1.Enabled = true
	Particle2.Enabled = true
	ParticleEmitter1.Enabled = true
	ParticleEmitter2.Enabled = true
	ParticleEmitter3.Enabled = true
	ParticleEmitter4.Enabled = true
	ParticleEmitter5.Enabled = true
	ParticleEmitter6.Enabled = true
	ParticleEmitter7.Enabled = true
	ParticleEmitter8.Enabled = true
	ParticleEmitter9.Enabled = true
	ParticleEmitter10.Enabled = true
	wait(0.1)
	Light.Enabled = false
	Particle1.Enabled = false
	Particle2.Enabled = false
	ParticleEmitter1.Enabled = false
	ParticleEmitter2.Enabled = false
	ParticleEmitter3.Enabled = false
	ParticleEmitter4.Enabled = false
	ParticleEmitter5.Enabled = false
	ParticleEmitter6.Enabled = false
	ParticleEmitter7.Enabled = false
	ParticleEmitter8.Enabled = false
	ParticleEmitter9.Enabled = false
	ParticleEmitter10.Enabled = false
	wait(cooldown)
	debounce = true
end)

Your code is very messy so I'll fix your code and try and fix your debounce

local debounce = false
local cooldown = 3
local Sound = script.Parent.Parent.Parent.taw.Sound
local Light = script.Parent.Parent.Parent.taw.Light

for i, particles in pairs(script.Parent.Parent.Parent.taw:GetDescendants()) do
	if particles:IsA("ParticleEmitter") then
		ParticleEmmiters = particles
	end
end

script.Parent.MouseClick:Connect(function()
	if debounce == false then
		debounce = true
	end
end
    Sound:Play()
    Light.Enabled = true
    ParticleEmmiters = true
    wait(0.1)
    Light.Enabled = false
    ParticleEmmiters = false
    wait(cooldown)
    debounce = false
end)

I don't know if this works but tell me if something doesn't work!

for debouce use

local debounce = false -- put this on the top

if not debounce then -- add this in function

debounce = true

debounce = false -- add this after wait
