Need help with macro

[wilykill]

Hey guys, so i am using this macro for the energy ring

500
{Immortal}
Self.Health%<=40 [jump]
Self.Equip.Ring(3051)
Exit()
Self.Health%<=50
{jump}
Self.UnEquip.Ring(0)
Exit()

And its perfect, but i wanted to use an other ring when this is not being use..
So use XXX ring if higher than X Hp and use this macro up here when lower than 50% hp
