try this:

PHP Code:

<?php
require('global.php');

mysql_select_db($database_msfdev, $msfdev);
$query_Recordset1 = "SELECT MAX(lastpost) FROM forum WHERE newsforum = 1 ";
$Recordset1 = $DB_site->query($query_Recordset1);
$row_Recordset1 = $DB_site->fetch_array($Recordset1);
$totalRows_Recordset1 = $DB_site->num_rows($Recordset1);
$lastupdate=$row_Recordset1['MAX(lastpost)'];

that should be what you wanted.
