$sql = "SELECT code,tittle,sum(price*number_dl) price,sum(number_dl) number_dl FROM `tblcmsportal` Group BY code,tittle ORDER BY `tblcmsportal`.`code` ASC ";
$hasil = mysql_query($sql,$conn);
//echo 'sql1'.$sql;
}else if($co_id>0){
$flagQ +=1;
$sql = "SELECT code,tittle,sum(price*number_dl) price,sum(number_dl) number_dl FROM `tblcmsportal` where co_id='$co_id' Group BY code,tittle ORDER BY `tblcmsportal`.`code` ASC ";
