Healbot and macro user advice

[Killandra]

Hi all,
i'm trying to make a quick heal macro and have it linked to my healbot. it basically casts unleash elements, nature's swiftness, and greater healing wave to give me a quick heal, but all it does is do the unleash elements and nature's swiftness; but does not cast greater healing wave
so far it looks like this:
/y Casting the Holy Crap Heal Button
/cast Unleash Elements
/cast Nature's Swiftness
/cast Greater Healing Wave

anybody know how i can edit this to make it cast greater healing wave?
thanks and Merry Winter Veil

Unless unleash elements is off the global cooldown, it will always only cast the first spell on the macro.
