player.spell(SPELL).charges

[Spem]

I can't seem to get this to work.

{"Corruption", "target.debuff(Corruption).duration <= 5", "target"},
{"Metamorphosis", "player.demonicfury >= 900" },
{"Hand of Gul'dan", "target.debuff(Hand of Gul'dan).duration <= 3", "target"},
{"Soul Fire", "player.spell(Molten Core).charges >= 4"},
{"Soul Fire", "target.health <= 25"},
{"Shadow Bolt" },

I am wanting the spell Soul Fire to only cast when it has 4 or more charges if Molten Core active at one time and then spamming it at less then 25% health and then using Shadow Bolt as the filler.
What currently happens is Soul Fire is only cast on below 25% and Shadow Bolt spammed - Corruption works fine, Hand of Gul'dan doesn't wait for the less then 3 second mark to hit the next cast.

If anyone could shed some light on what i am doing wrong that would be fantastic!

Fixed it.

{"Soul Fire", "player.buff(Molten Core).count >= 4"},

That is the correct command.
