As you can see by my screen shot, the totals in echo are fine, however trying to save them to the total fields is wrong.
I tried Identifying the fields with " or ', but that errors out the page. Anyone ? I am missing something simple I am sure,
probably to much coding and my mind is mud <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=10290&image=1&table=forumtopics' class='bbc_emoticon' alt=':)' />

[codebox]global $data,$data1,$conn,$strTableName;
$str = "select sum(Order_sub_total) + sum(Tax_Amount) + sum(Delivery_cost) from order_sales where Order_num=".$keys["Order_num"];
$rs = db_query($str,$conn);
$data = db_fetch_numarray($rs);
$value = $data[0];
$str1 = "select sum(Order_sub_total) + sum(Tax_Amount) + sum(Delivery_cost)- sum(Amount_down) from order_sales where Order_num=".$keys["Order_num"];
$rs1 = db_query($str1,$conn);
$data1 = db_fetch_numarray($rs1);
$value1 = $data1[0];
//$values ["Total_due"] = $value1;
//$values ["Order_total"] = $value;
$strUpdate = "update order_sales set Order_total =".$value[0]." where Order_num=".$keys["Order_num"];
$strUpdate = "update order_sales set Total_due =".$value1[0]." where Order_num=".$keys["Order_num"];
db_exec($strUpdate,$conn);
echo ($value1);
echo "//__||";
echo ($value);
