Spellbook not working! 1.2

[Aeronx]

Hello all! I dont know why, but it doesnt work for me, i get this error!

data/actions/scripts/other/spellbook.lua:onUse
data/actions/scripts/other/spellbook.lua:18 bad argument #1 to 'pairs' <table expected, got nil>
Stack traceback:
            [C]: ?
            [C]: in function 'pairs'

I didnt do anything to the code, its the default script that comes with the engine. Any clues?

function onUse(player, item, fromPosition, target, toPosition, isHotkey)
local count = getPlayerInstantSpellCount(player)
local text = ""
local spells = {}
for i = 0, count - 1 do
local spell = getPlayerInstantSpellInfo(player, i)
if spell.level ~= 0 then
if spell.manapercent > 0 then
spell.mana = spell.manapercent .. "%"
end
spells[#spells + 1] = spell
end
end

table.sort(spells, function(a, b) return a.level < b.level end)

local prevLevel = -1
for i, spell in ipairs(t) do
local line = ""
if prevLevel ~= spell.level then
if i ~= 1 then
line = "\n"
end
line = line .. "Spells for Level " .. spell.level .. "\n"
prevLevel = spell.level
end
text = text .. line .. " " .. spell.words .. " - " .. spell.name .. " : " .. spell.mana .. "\n"
end

player:showTextDialog(item:getId(), text)
return true
end

Thanks for you time!
