Here I edit the code so it will work. You may have to edit the table color to match your site.

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

{
    if (document.getElementById('uploadfield').value != '' && document.getElementById('title').value != '')

        document.getElementById('uploadbusy').style.display = 'block';
    }
}
//-->
