errore document.getElementById

[Ajeje Brazof]

Funziona tutto ma il browser mi segnala un errore alla riga:
document.getElementById('update_seconds').innerHTM L = results[4];

Da cosa potrebbe essere dato?
Il codice fa parte di uno script in ajax per un shoutbox/chat

    <script type="text/javascript">
    <!--

    var post_time = {TIME};
    var read_interval = 15000;
    var interval = setInterval('handle_send("read", last_id);', read_interval);

    function handle_send(mode, f)
    {

Nell'html il campo con id="update_seconds" non esiste.

Quindi posso cancellare quella riga senza riscontrare problemi?
