Lua Problem with script

[Aldruh]

I have a problem with a script pokemon, here a screenshot :

The server remains locked and the screen is filled with that mistake many times,
anyone knows of it ?

local msgs = {"use ", ""}

function doAlertReady(cid, id, movename, n, cd)
    if not isCreature(cid) then return true end
    local myball = getPlayerSlotItem(cid, 8)
    if myball.itemid > 0 and getItemAttribute(myball.uid, cd) == "cd:"..id.."" then
        doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, getPokeballName(myball.uid).." - "..movename.." (m"..n..") is ready!")
    return true
    end
    local p = getPokeballsInContainer(getPlayerSlotItem(cid, 3).uid)
    if not p or #p <= 0 then return true end
    for a = 1, #p do
        if getItemAttribute(p[a], cd) == "cd:"..id.."" then
            doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, getPokeballName(p[a]).." - "..movename.." (m"..n..") is ready!")
        return true
