Classe funzione e query

[DESIGNER Belo]

Ciao,

in un file php ho inserito una classe che contiene degli script che poi dovro richiamare in un'altra pagina..

vi posto la classe

class menus{
function visualizza(){
require_once('Connections/macrame_connect.php');
$colname_menu_dx = "1";
if (isset($_GET['area'])) {
  $colname_menu_dx = (get_magic_quotes_gpc()) ? $_GET['area'] : addslashes($_GET['area']);
}
mysql_select_db($database_macrame_connect, $macrame_connect);
$query_menu_dx = sprintf("SELECT * FROM menu WHERE ID_area = %s ORDER BY posizione ASC", $colname_menu_dx);
$menu_dx = mysql_query($query_menu_dx, $macrame_connect) or die(mysql_error());
$row_menu_dx = mysql_fetch_assoc($menu_dx);
$totalRows_menu_dx = mysql_num_rows($menu_dx);

echo "<table width=\"240\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">";
 echo " <tr>
    <td width=96 valign=top>[url="template_menu2.php?ills="]<img src=img/icone/  $row_menu_dx[icona];  border=0>[/url]</td>
    <td width=143 valign=top><table width=144 border=0 cellspacing=0 cellpadding=0>
        <tr>
          <td height=12></td>
        </tr>
        <tr>
          <td valign=top><span class=testo-aree>[b]  $row_menu_dx[titolo]; [/b]

                $row_menu_dx[descrizione]; </span></td>
        </tr>
    </table></td>
  </tr>
   
  <tr bgcolor=cccccc>
    <td height=1></td>
    <td height=1></td>
  </tr>" ;
  
    
echo"</table>";




}} 

Perchè la query da errore?
se la tolgo dalla classe tutto funziona



ecco l'errore

Warning: mysql_select_db(): supplied argument is not a valid MySQL-Link resource in xxxx\menu_dx.php on line 11

Warning: mysql_query(): supplied argument is not a valid MySQL-Link resource in xxxx\menu_dx.php on line 13
