Page don´t reload or redirect

Hi,
My goal is to refresh/reload the current page after sending a mail and updating two tables when the custom button in the list view page is pressed.
Put the following code in custom button's events :

• On server :
  
  global $dal;
  
  $dal_TableName = $dal->Table("litigios");
  
  $body="";
  
  foreach(@$keys as $keyblock)
  
  {
  
  $arr=explode("&",refine($keyblock["LIT_ID"]));
  
  if(count($arr)<1)
  
  continue;
  
  $arr2=array();
  
  $arr2["LIT_ID"]=urldecode(@$arr[0]);
  
  $where = KeyWhere($arr2);
  
  $rstmp = $dal_TableName->Query($where,"");
  
  $datatmp=db_fetch_array($rstmp );
  
  $body .= "------------------------------------------------------------\n";
  
  $body .= "ID: " . $datatmp['LIT_ID'] . "\n";
  
  $body .= "Loja: " . $datatmp['LIT_LOJA'] . "\n";
  
  $body .= "Data: " . $datatmp['LIT_DATA'] . "\n";
  
  $body .= "Tipo: " . $datatmp['LIT_TIP'] . "\n";
  
  $body .= "Contacto: " . $datatmp['LIT_CONTACTO'] . "\n";
  
  $body .= "E-Mail: " . $datatmp['LIT_MAIL'] . "\n------------------------------------------------------------\n";
  
  }
  // send the email
  
  $email="sribeiro@cooplecnorte.pt";
  
  $subject="Novo(s) Litígio(s)";
  
  $arr = runner_mail(array('to' => $email, 'subject' => $subject,
  
  'body' => $body));
  
  $result["txt"] = "Litigio(s) Enviado(s).";
  // if error happened print a message on the web page
  
  if (!$arr["mailed"])
  
  {
  
  $errmsg = "Erro:
  ";
  
  $errmsg.= "Ficheiro: " . $arr["errors"][0]["file"] . "
  ";
  
  $errmsg.= "Linha: " . $arr["errors"][0]["line"] . "
  ";
  
  $errmsg.= "Descrição: " . $arr["errors"][0]["description"] . "
  ";
  
  $result["txt"] = $errmsg;
  
  }
  global $dal;
  
  for ($i=0; $i<count($keys); $i++)
  
  {
  
  $sql = "Update litigios set LIT_ESTADO=1 where LIT_ID="
  
  . $keys[$i]["LIT_ID"];
  
  CustomQuery($sql);
  
  }
  global $dal;
  
  for ($i=0; $i<count($keys); $i++)
  
  {
  
  $sql = "Update vloja set LIT_ESTADO=1 where LIT_IDL="
  
  . $keys[$i]["LIT_ID"];
  
  CustomQuery($sql);
  
  }
  Mail is sent, tables are updated.
  How can i refresh/reload the list view after those two actions ?
  Many thanks.
  Sérgio
