How do i make my punch-script make damage when it touches someone? [....hello....]

So to expand, i created a script that whenever you press on this tool, it fires an animation and takes damage on another player that got punched.

The error is that is it's not damaging me at all.

I know it's badly formatted, but I'm trying my best, and whats optimal for you guys.

The Local Script:

local Animation = script.Animation
local Replicated = game:GetService("ReplicatedStorage")
local RemoteEvent = Replicated.Remotes.Punch

local Debounce = false

wait(2)

local Humanoid = game.Players.LocalPlayer.Character.Humanoid

script.Parent.Activated:Connect(function()
	if not Debounce then
		Debounce = true
	
	local AnimationTrack = Humanoid:LoadAnimation(Animation)
	RemoteEvent:FireServer()
	wait(2)
	Debounce = false 
	end
end)

The Script:

local Tools = game:GetService("ReplicatedStorage"):WaitForChild("Tools")
local RemoteEvent = game:GetService("ReplicatedStorage").Remotes.Punch
local Animation = Tools.SuperPunch.PunchConnecter.Animation

wait(1)

RemoteEvent.OnServerEvent:Connect(function(player)
	local Hum = player.Character.Humanoid
	local AnimationTrack = Hum:LoadAnimation(Animation)
	AnimationTrack:Play()
	print("Hello!")
	
	if AnimationTrack.IsPlaying then
		local LeftArm = player.Character["RightHand"]
		
		LeftArm.Touched:Connect(function(hit)
			if hit.Parent:FindFirstChild("Humanoid") and game.Workspace:FindFirstChild(hit.Parent) then
				Hum:TakeDamage(0)
				if hit.Parent:FindFirstChild("Humanoid") and not game.Workspace:FindFirstChild(hit.Parent) then
					Hum:TakeDamage(20)
					Hum.Sit = true
					
				
	end
	end
	end)
		end
		end)
