when i activate my script nothing happens can you fix it?

essentially the melee attack isnt doing anything i press e and nothing happens its like the script doesnt run

--//Titan Shift

script.Parent.Shift.OnServerEvent:Connect(function(Player)


    NewChar = game.ReplicatedStorage.BasicAttackTitan:Clone()
    local Pos = Player.Character:GetPrimaryPartCFrame()

    Player.Character:Destroy()
    Player.Character = NewChar
    NewChar.Parent = workspace
    NewChar:SetPrimaryPartCFrame(Pos)
end)

--//Melee Attack

local Attack1 = script.Attack1
local Attack2 = script.Attack2
local ComSeq = 1
local anim
local Hitbox = game.ServerStorage.HitBox


script.Parent.Melee.OnServerEvent:Connect(function()


    print(NewChar)

    local hum = NewChar.Humanoid
    local Humrp = NewChar.HumanoidRootPart
        local anim1 = hum:LoadAnimation(Attack1)
        local anim2 = hum:LoadAnimation(Attack2)



        if ComSeq == 1 then
            anim = anim1
            ComSeq = 2

        elseif ComSeq == 2 then
            anim = anim2
            ComSeq = 1

        end

        anim:Play()

        local HitboxNew = Hitbox:Clone()
        local Weld = Instance.new("WeldConstraint")
        Weld.Parent = Humrp
        Weld.Part0 = Humrp
        Weld.Part1 = HitboxNew

        HitboxNew.CFrame = Humrp.CFrame * CFrame.new(0,0,-3)
        HitboxNew.Parent = Humrp

        local touchConn

        touchConn = HitboxNew.touched:Connect(function(hit)
        if hit.Parent.Name ~= NewChar.Name and hit.Parent.Humanoid then

                HitboxNew:Destroy()
                Weld:Destroy()
                hum.Health -= 100

            end 
        end)
        wait(0.5)
        if touchConn ~= nil then touchConn:Disconnect() end
        Weld:Destroy()
        HitboxNew:Destroy()
end)
