LUA Argument list? also a LUA script error.

[handofoberon]

I was wondering if anyone has a list with all the WoW arcemu lua function arguments.
ex:

function This_Function(Unit, event)

I also get an error(:3: attempt to index local 'player' (a number value)) whenever a spell is cast with

function Damage_Or_Heal(Unit, event, player)

if(player:GetCurrentSpellId() == 49895) then
    if(Unit:IsFriendly(target) == "True") then
        Player:Heal(Unit, 49895, 665)
        player:SendAreaTriggerMessage("All skills at max Have fun!")
    end
    if(Unit:IsFriendly(target) == "False")then
        Unit:DealDamage(Unit, 443, 49895)
    end
end
end

RegisterServerHook(10, "Damage_Or_Heal")
