$objConnect = mysql_connect("localhost","prcs_root","admin1q2w3e4r") or die("Error Connect to Database");
$objDB = mysql_select_db("prcs_db");
$strSQL = "UPDATE std_as SET ";
$strSQL .="sopass = '".$_POST["txtsopass"]."' ";
$strSQL .=",soname = '".$_POST["txtsoname"]."' ";
$strSQL .=",solname = '".$_POST["txtsolname"]."' ";
$strSQL .=",sonum = '".$_POST["txtsonum"]."' ";

$strSQL .="WHERE sopass = '".$_GET["CusID"]."' ";
$objQuery = mysql_query($strSQL);
if($objQuery)
{
	echo "Save Done.";
	echo "<meta http-equiv='refresh' content='3;URL= index.php'>";
}
else
