Why is hit a nil value in this script?

--BaseBall Bat script made by Cyotokatrov.
script.Parent.Equipped:connect(function(m)
        m.Button1Down:connect(function(hit)
            script.Parent.Parent.SmackAnim.Disabled = false
            if game.Players.LocalPlayer.PlayerGui.StrengthGui.Strength == 20 then
                script.Parent.HittingPart.Damage.MinValue = script.Parent.HittingPart.Damage.MinValue + 20
                script.Parent.HittingPart.Damage.Value = script.Parent.HittingPart.Damage.Value + 20
            end

                script.Parent.HittingPart.Damage.MinValue = script.Parent.HittingPart.Damage.MinValue + 40

                script.Parent.HittingPart.Damage.Value = script.Parent.HittingPart.Damage.Value + 60 --capped at right here anything else is too OP. this is OP enough.

Everything's working smoothly except for my hit function. Why is that?
