This is my save.lua file:

local savingEvent = 0

local function save(delay)
    doSaveServer()
    if(delay > 0) then
        savingEvent = addEvent(save, delay, delay)
    end
end

function onSay(cid, words, param, channel)
    local tmp = tonumber(param)
    if(tmp ~= nil) then
        stopEvent(savingEvent)
        save(tmp * 60 * 1000)
    elseif(param == '') then
        doSaveServer(false)
    else
        local tid = getPlayerByNameWildcard(param)
        if(not tid or (isPlayerGhost(tid) and getPlayerGhostAccess(tid) > getPlayerGhostAccess(cid))) then
            doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Player " .. param .. " not found.")
