How to combine these two Scripts?

I have this code

local plr = game:GetService('Players').LocalPlayer
	local backpack = plr:WaitForChild("Backpack")
	 
	for i, v in pairs(backpack:GetChildren()) do
	    if v:IsA("Tool") then
	        v:Destroy()
	    end
	end

that was given to me by ColdFoxy07(big thanks) and I have This code that I edited

local cooldown = false --//r
	local button = script.Parent
	local plr = game:GetService('Players').LocalPlayer
	local tool = game.ReplicatedStorage.ACS_Engine.HOOD["Micro UZI"]
	 
	button.Activated:Connect(function()
	    if cooldown == false then
	        cooldown = true
	    script.Parent.Parent.Visible = false
	    plr.Backpack:FindFirstChildWhichIsA('Tool'):Destroy()
	    local clone = tool
	    clone.Parent = plr.Backpack
	    wait(0.5)
	    script.Parent.Parent.Parent.ClassH.Visible = true
	    wait(3)
	        script.Parent.Parent.Parent.ClassH.Visible = false
	        cooldown = false
	        end
	    end)

and Im trying to put the two together. but it doesent work here is the code( that I made trying to put the two together)

local cooldown = false --//r
	local button = script.Parent
	local plr = game:GetService('Players').LocalPlayer
	local tool = game.ReplicatedStorage.ACS_Engine.HOOD["Micro UZI"]
local backpack = plr:WaitForChild("Backpack")
	 
	button.Activated:Connect(function()
	    if cooldown == false then
	        cooldown = true
	    script.Parent.Parent.Visible = false
	 for i, v in pairs(backpack:GetChildren()) do
	    if v:IsA("Tool") then
	        v:Destroy()
	    local clone = tool
	    clone.Parent = plr.Backpack
	    wait(0.5)
	    script.Parent.Parent.Parent.ClassH.Visible = true
	    wait(3)
	        script.Parent.Parent.Parent.ClassH.Visible = false
