Lua Help with for(spell)

[Fairbanks]

My first time trying to create spells with the FOR,of course,made it wrong,and don't know to fix it :$
What i wanted to happen:
A random wave of burning arrows going from the player ( Its going into the player )
40 numbers of effect ( Only happens 1 )
HIT ( It doesn't hit )

If anyone could help,thanks

local effect = {[1] = 33, [2] = 3}
function onCastSpell(cid, var)
    for a = 1, 40 do
            doAreaCombatHealth (300, cid, getPlayerLookPos(cid), doSendDistanceShoot({x = getCreaturePosition(cid).x + math.random(-7, 7), y = getCreaturePosition(cid).y + math.random(-6, 6), z = getCreaturePosition(cid).z}, getCreaturePosition(cid), effect[math.random(1,2)]), -800, -1500)
            return true
    end
end

fast please,need my beauty sleep
