Logic error in form submision - Create Company Form

Refer to the lines 303-312 in admin/create_coy.php :-
        <script language='javascript'>
        function updateCompany() {
            if (document.forms[0].uploadfile.value!='' && document.forms[0].dbname.value!='') {
                document.forms[0].action='create_coy.php?c=u&ul=1&id=" . $n . "&fn=' + document.forms[0].uploadfile.value
            }
            else {
                document.forms[0].action='create_coy.php?c=u&id=" . $n . "&fn=' + document.forms[0].uploadfile.value
            }
            document.forms[0].submit()
        }

The else statement alludes to uploadfile.value when it is non-existent.
