My animation code is not working and there are no errors, how can I fix this?

--Services
local Players = game:GetService("Players")

--Modules
--Constants
local Character = script.Parent
local Humanoid = Character:FindFirstChildOfClass("Humanoid")
local Player = Players:GetPlayerFromCharacter(Character)

--Variables
local CurrentTool
local CurrentFunc

--Functions
--Main
Character.ChildAdded:Connect(function(o)
    if o:IsA("Tool") then
        CurrentTool = o
        if CurrentFunc then CurrentFunc:Disconnect() end 
        local Animations = o:FindFirstChild("Animations")
        if Animations then
            local TestAnimation = Animations:FindFirstChild("Main")
            if not TestAnimation then return end  
            CurrentFunc = o.Activated:Connect(function()
                local Test = Humanoid:FindFirstChildOfClass("Animator"):LoadAnimation(TestAnimation)
                Test:Play()
            end)
        end
    end
end)
