Tool breaks when I clone it into the players inventory?

So as you can tell from the title, I used .AncestryChanged and .CharacterAdded as an attempt to fix my problem, but it didn't work.The scripts inside the tool break when the tool is cloned into the player's backpack.

The gun is cloned from the ServerStorage by a ServerScript in ServerScriptService. No errors, either.

Sorry if the the script is long.

local mouse = game.Players.LocalPlayer:GetMouse()local spread = .75
local ts = game:GetService("TweenService")
local ti = TweenInfo.new(0.5,Enum.EasingStyle.Elastic,Enum.EasingDirection.Out,0,true,0)
local ti2 = TweenInfo.new(1,Enum.EasingStyle.Linear,Enum.EasingDirection.Out,0,false,0)
local cam = workspace.CurrentCamera
local canFire = true
local fireRate = 2
local uis = game:GetService("UserInputService")
local reloading = false
local player = game.Players.LocalPlayer
local char = game.Players.LocalPlayer.CharacterAdded:Wait()
local hum = char:WaitForChild("Humanoid")
local lockMouse = false

local hold = hum:LoadAnimation(script.Parent.hold)

local canTouch = true

script.Parent.Activated:Connect(function()
	if reloading == false then
		if canFire == true and reloading == false then
			canFire = false
			local CameraShaker = require(game.ReplicatedStorage.CameraShaker)
			local camera = workspace.CurrentCamera
			local camShake = CameraShaker.new(Enum.RenderPriority.Camera.Value, function(shakeCf)
				camera.CFrame = camera.CFrame * shakeCf
			end)
			camShake:Start()
			camShake:Shake(CameraShaker.Presets.Explosion)
			script.Parent.Handle.laser:Play()
			script.Parent.Bullet:FireServer(mouse.Hit.p,ti2,ts)
			wait(fireRate)
			canTouch = true
			canFire = true
		end
	end
end)
script.Parent.Equipped:Connect(function(mouse)
	hold:Play()
	uis.MouseIconEnabled = false
	player.PlayerGui:WaitForChild("Aim").Enabled = true
end)
script.Parent.Unequipped:Connect(function()
	hold:Stop()
	uis.MouseIconEnabled = true
	player.PlayerGui:WaitForChild("Aim").Enabled = false
end)

I have zero idea on why this is happening. Help please!
