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)

WeakHitbox

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