Why Don't My Attacks Work?

I'm working on a fighting game and i'm tryna code attacks, for some reason, the attack doesn't deal any damage,

ATK1 (LocalScript)

local ContextActionService = game:GetService("ContextActionService")
local plr = game.Players.LocalPlayer
local function ATK1(actionName, inputState, inputObject)
	if plr.Team == game.Teams.Lobby then
		print("not attacking :D")
	else
	if inputState == Enum.UserInputState.Begin then
		if plr.ATK1.Value == 1 then
			local A = Instance.new("Animation", plr.Character)
			A.AnimationId = "rbxassetid://5702590570" --Replace 000 with the numbers at the end of the link to your animation.
			local track = plr.Character.Humanoid:LoadAnimation(A)
			track:Play()
			local hit = plr.WeakHitbox:Clone()
			hit.Parent = plr.Character["Left Arm"]
			plr.Character.Humanoid:UnequipTools()
			wait(0.3)
			hit:Destroy()
		end
		if plr.ATK1.Value == 2 then
			local A = Instance.new("Animation", plr.Character)
			A.AnimationId = "rbxassetid://5709400160" --Replace 000 with the numbers at the end of the link to your animation.
			local track = plr.Character.Humanoid:LoadAnimation(A)
			track:Play()
			local hit = plr.WeakHitbox:Clone()
			hit.Parent = plr.Character["Left Arm"]
			plr.Character.Humanoid:UnequipTools()
			wait(0.3)
			hit:Destroy()
		end
		end
	end
end

ContextActionService:BindAction("ATK1", ATK1, false, Enum.KeyCode.ButtonX, Enum.KeyCode.Z)

local UserInputService = game:GetService("UserInputService")
game.Players.PlayerAdded:connect(function(player) 
	local atk1 = game.ServerStorage.ATK1:Clone()

		else
			if player.ATK1.Value == 1 then
				local ATK = game.ServerStorage.ATK.Punch:Clone()
				ATK.Parent = player.Backpack
			end
			if player.ATK1.Value == 2 then
				local ATK = game.ServerStorage.ATK["Spin Arm"]:Clone()
				ATK.Parent = player.Backpack
			end
			if player.ATK2.Value == 1 then
				local ATK = game.ServerStorage.ATK.Clap:Clone()
				ATK.Parent = player.Backpack

				ATK.Parent = player.Backpack

	end)

WeakHitbox

script.Parent.Touched:connect(function(hit)
	if hit and hit.Parent and hit.Parent:FindFirstChild("Humanoid") then
		hit.Parent.Humanoid:TakeDamage(4)
	end
