    Sum of numbers that was insert will automatic compute and appear in total text field

    Good day!

    I have a problem in adding codes in my php codes, but I have the concept of codes that I want to add in my php codes, but I don't know if it is right. Kindly check my codes thank you.


    And here is the code I want to add:
    Code:
    <?php
    
    $rexist = 0;
    if($_POST["clt_no"])
    {
       $opname = $_POST["opname"];
       $inqty = $_POST["inqty"];
       $outqty = $_POST["outqty"];
       
       $totalarr = count($opname) - 1;
        for($ctr=0; $ctr < $totalarr; $ctr++)
            {
            $inqty[$ctr] = (float) $inqty[$ctr];
            $outqtyqty[$ctr] = (float) $outqty[$ctr];
            
             $query = "INSERT INTO clt_traceability (operation_name, input_qty, clt_transact_id) VALUES ('" . $opname[$ctr] . "',  '" . $inqty[$ctr] . "', '" . $outqty[$ctr] . "', '" . $clt_transact_id . "')";
            $result = mysql_query($query);
            }   
            
        $query = "SELECT * FROM clt_transact WHERE  clt_no = '" . $_POST["clt_no"] . "'";

    I want to happen be in operation1 and operation 2 the input qty and output qty will automatically compute the sum and the result will appear in the total.
    I don't know how thus the result should be appearing automatically in the total textfield. I mean is the sum of input qty of operation 1 will automatic appear in operation1_total and also with the output qty, same with the operation2.

    I got this error:
    Warning: mysql_query() [function.mysql-query]: Access denied for user 'ODBC'@'localhost' (using password: NO) in D:\xampp\htdocs\sumtot.php on line 164

    Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in D:\xampp\htdocs\sumtot.php on line 164
    Kindly tell me what is missing or wrong.

    Thank you

    mysql_connect($host,$user,$password);
