I have this spellup script that show all spells avaliable to buy to your magic level, when u get one more magic level:

--[[------------------------------------------------<|]

local s = { --SETUP
    repeatAfterDeath = true, -- true -> player will always get the msg at lvlup | false -> player will only get the 1st time the gets the new level
-- storage below is where the newlevel will be stored ONLY IF YOU USE repeatAfterDeath
    Storage = 10000,
    messageType = 'popUp', -- options: 'popUp' or 'channel'
--this one below only used if messageType = channel
    channelClass = MESSAGE_EVENT_ORANGE
}
   
function onAdvance(cid, skill, oldlevel, newlevel)
    if skill ~= 7 or not s.repeatAfterDeath and getCreatureStorage(cid, s.Storage) >= newlevel then
        return true
    end
 
    local t = {}
    for i = 0, getPlayerInstantSpellCount(cid) - 1 do
        local spell = getPlayerInstantSpellInfo(cid, i)
        if(spell.mlevel ~= 0) and spell.mlevel == newlevel then
            if(spell.manapercent > 0) then
                spell.mana = spell.manapercent .. '%'
            end
            table.insert(t, spell)
        end
    end

    table.sort(t, function(a, b) return a.level < b.level end)
    local tmpStr = ''
    local Str = ''
    for i, spell in ipairs(t) do
        tmpStr = 'NEW SPELL:\n['..spell.name..'] "'..spell.words..'"\n\n'
        Str = Str .. tmpStr
    end
 
    if Str == '' then
        return true
    end
 
    doCreatureSetStorage(cid, s.Storage, newlevel)
    if s.messageType == 'popUp' then
        doShowTextDialog(cid, 2175, Str)
    elseif s.messageType == 'channel' then
        doPlayerSendTextMessage(cid, s.channelClass, Str)
    end
    return true
end

i tried to create a !spells based on that script /\
to show all spells your vocation could use:

function onSay(cid, words, param, channel)
    local t = {}
    for i = 0, getPlayerInstantSpellCount(cid) - 1 do
        local spell = getPlayerInstantSpellInfo(cid, i)
        if(spell.manapercent > 0) then
            spell.mana = spell.manapercent .. '%'
        end
        table.insert(t, spell)
    end

    table.sort(t, function(a, b) return a.level < b.level end)
    local tmpStr = ''
    local Str = ''
    for i, spell in ipairs(t) do
        tmpStr = '('..i..'):\n['..spell.name..'] "'..spell.words..'"\n\n'
        Str = Str .. tmpStr
    end

    doShowTextDialog(cid, 2175, Str)
    return true
end

but it is not showing not even one spell...
why?
