My weapon system doesnt function as intended?

Im trying to make a tool with an attack animation and a cooldown, my system may be funky but if you can help please do. It tells me there are no errors but it doesnt deal damage to the dummy and the cooldown doesnt exist.

function attack()
    script.Parent.Handle.Touched:Connect(function(hit)
        if hit.Parent:FindFirstChild("Humanoid") then
            hit.Parent.Humanoid:TakeDamage(30)

            warn("Hit successful")

        end
    end)
end

script.Parent.Equipped:Connect(function(Mouse)
    Mouse.Button1Down:Connect(function()
        local animation = game.Players.LocalPlayer.Character.Humanoid:LoadAnimation(script.Parent.Animation)
        animation:Play()
        attack()
        script.Disabled = true
        wait(3)
        script.Disabled = false
    end)
end)
