I am trying to make a button only work when a bindable event fires but it does not work?

local BindableEvent = game.ReplicatedFirst:WaitForChild("Clickable")
local Debounce = true

BindableEvent.Event:Connect(function()
	Debounce = false
end)

if not Debounce then
function onClicked()
    Game.Workspace.TalentPack.Lighting.Buz3.BrickColor = BrickColor.new("Bright red")
    Game.Workspace.TalentPack.Lighting.Buz4.BrickColor = BrickColor.new("Bright red")
    Game.Workspace.TalentPack.Lighting.Buz9.BrickColor = BrickColor.new("Bright red")
    Game.Workspace.TalentPack.Lighting.Buz10.BrickColor = BrickColor.new("Bright red")
	game.Lighting.Ambient=Color3.new(1,0,0)
	Debounce = true
    wait(3)
	game.Lighting.Ambient=Color3.new(0,0,0)
end
script.Parent.ClickDetector.MouseClick:connect (onClicked)
