Add uniqueid on this script

[Bruce Leal]

local levelReward = {
    [30] = 3,
    [50] = 5,
    [100] = 10
}

function onAdvance(cid, skill, oldLevel, newLevel)
    doCreatureAddHealth(cid, getCreatureHealth(cid))
    doCreatureAddMana(cid, getCreatureMana(cid))

    for k, v in pairs(levelReward) do
        if newLevel == k and getPlayerStorageValue(cid, 3746) < k then
            doPlayerAddItem(cid, 2160, v, TRUE)
            doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Congratulations, you\'ve received "..v.." crystal coins as a reward for level "..k..".")
     
            setPlayerStorageValue(cid, 3746, k)
        end
    end
    return true
end

local levelReward = {
    [7] = {itemid = 2160, amount = 3, storage = 1},
    [8] = {itemid = 2160, amount = 5, storage = 2},
    [30] = {itemid = 2160, amount = 1, storage = 3},
    [50] = {itemid = 2160, amount = 1, storage = 4}
}
local storage = 10000
function onAdvance(cid, skill, oldLevel, newLevel)
    doCreatureAddHealth(cid, getCreatureHealth(cid))
    doCreatureAddMana(cid, getCreatureMana(cid))
    if skill == SKILL_LEVEL and newLevel > oldLevel then
 
    if getPlayerStorageValue(cid, storage) == nil or getPlayerStorageValue(cid, storage) == -1 then
        setPlayerStorageValue(cid, storage, 0)
    end
 
        for i, v in pairs(levelReward) do
            if newLevel == i and getPlayerStorageValue(cid, storage) < levelReward[v].storage then
                doPlayerAddItem(cid, levelReward[v].itemid, levelReward[v].amount, TRUE)
                doBroadcastMessage("Pelos deuses, " .. getCreatureName(cid) .. " recebeu "..levelReward[v].amount.." "..getItemNameById(levelReward[v].itemid).." como recompensa por adquirir o nivel "..k..".", MSG_STATUS_CONSOLE_ORANGE)
                setPlayerStorageValue(cid, storage, getPlayerStorageValue(cid, storage) + 1)
            end
        end
    end
    return true
end
