[Lua] Help

[Pedregon]

I'm trying to get an NPC cast a buff on it's self, i'm very new to LUA, not sure how everything works.
so here's the script.

local NPC_ID = 21750

function OrcWarlock_OnCombat(pUnit, Event)
        pUnit:SendChatMessage(14, 0, "Summoning Warriors of the Horde...")
        pUnit:RegisterEvent(OrcWarlock_DA, 1000, 1) -- Gul'dan Channel
        
end

function OrcWarlock_DA(pUnit, Event)
        pUnit:CastSpell(35996)
end

Not sure what's wrong with it, if anyone can help me correct it i'll + 4 rep :] Thanks.

EDIT:

Added new script, loads but doesn't work in game.

Why is there space after the comma that follows the spell you cast. And you can't have spaces in teh names of functions I believe. What errors do you get on start up?

scripts/Orc Warlock.lua:7: '<' expected near 'Warlock_Gul'

[Dr. Livingstone]

The new script needs the function to be registered.
