Help with resetting a combo system

I’m making a sword in my game and I want it to have a combo system. I’ve figured out a way to make combos work but I cant find a way to make it resets when the player did not do the 2nd hit on time. This is the script that im using.

Local Script:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local sword = player.Character:WaitForChild("Handle")
local event = game.ReplicatedStorage.Clicks
local loadanim = player.Character.Humanoid:LoadAnimation(sword.Anims.click1)
local loadanim2 = player.Character.Humanoid:LoadAnimation(sword.Anims.click2)

local function combo()
	for i, v in pairs(sword.Blade:GetChildren()) do
		if v:IsA("ParticleEmitter") then
			for a, e in pairs(sword.Blade:GetChildren()) do
				if e:IsA("Trail") then
					event:FireServer(v, e, loadanim, sword)
					loadanim:Play()
				end
			end
		end
	end
end

local function combo2()
	for i, v in pairs(sword.Blade:GetChildren()) do
		if v:IsA("ParticleEmitter") then
			for a, e in pairs(sword.Blade:GetChildren()) do
				if e:IsA("Trail") then
					event:FireServer(v, e, loadanim, sword)
					loadanim2:Play()
				end
			end
		end
	end
end

local debounce = false
comboamount = 0
mouse.Button1Down:Connect(function()
	if debounce == false and comboamount == 0 then
		debounce = true
		combo()
		comboamount = 1
		wait(.6)
		debounce = false
	elseif debounce == false and comboamount == 1 then
		debounce = true
		combo2()
		wait(.6)
		debounce = false
	end
end)

Server Script:

local event = game.ReplicatedStorage.Clicks
event.OnServerEvent:Connect(function(player, v, e, loadanim, sword)
	local sound = sword.Slash
	v.Enabled = true
	e.Enabled = true
	sound:Play()
	player.Character.Humanoid.WalkSpeed = 5
	wait(.7)
	v.Enabled = false
	e.Enabled = false
	player.Character.Humanoid.WalkSpeed = 16
end)
