[SOLVED] My punch script does not respond to a block animation, any help?

So basically, I have a punch script, that is meant to take damage from a humanoid and if an animation is playing it will not.

Script:

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local humanoid = player.Character:FindFirstChild("Humanoid")
local animate
local part = humanoid.Parent:WaitForChild("RightHand")
local connection
local db = false
local animated

local function round(n)
	return math.floor(n + 0.5)
end

part.Touched:Connect(function(hit)
	if db == false then
		--Cannot Punch
	elseif db == true then
		if hit.Parent.Humanoid then
			**if not hit.Parent.LocalAnimation then**
				hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - round(player.leaderstat.Strength.Value / 100)
				print("Hit")
				local animator = Instance.new("Animation", hit.Parent)
				animator.AnimationId = "rbxassetid://5390143931"
				animated = hit.Parent.Humanoid:LoadAnimation(animator)
				animated:Play()
				db = false
			end
		else
			print("Not a humanoid!")
		end
	end
end)

mouse.KeyDown:Connect(function(key)
	if key == "z" then
		local animation = Instance.new("Animation", player.Character)
		animation.AnimationId = "rbxassetid://5390069207"
		animation.Name = "PunchAnim"
		animate = humanoid:LoadAnimation(animation)
		animate:Play()
		game.ReplicatedStorage.Event.AddStrength:FireServer()
		db = true
		wait(0.5)
		db = false		
	end
end)	

It keeps saying error at the line with asterisks, that is line 18.

EDIT: Sorry I meant line 19
