Auto calculate inside while loop

I just want to know if it is possible to have an autocalculate in a textboxes inside while loop?and if it is possible how?..

here is my code:

<style type="text/css">
    position: relative;
    width: 20%;
<link rel="stylesheet" type="text/css" href="kanban.css" />
<script type="text/javascript">

function display_PS(){
function display_Kanban(){
$con = mysql_connect('localhost', 'root','');

if (!$con) {
    echo 'failed';

mysql_select_db("mes", $con);

<form name="loading_kanban">
<div id="main_button">
<!--<label style="margin-left: .9em; font-family: Arial, Helvetica, sans-serif; font-size: .7em;">Display Details:</label><input  onclick='showDetails(this);' id='chkDetail'   type='checkbox' checked='checked' value='wip'/>     -->
<input type="button" name="parameter_settings" value="Parameter Settings" onclick="display_PS()">
<input type="button" name="parameter_settings" value="Stock Requisition">
<input type="button" name="parameter_settings" value="Kanban Report" onclick="display_Kanban()">
<div id="fieldset_PS">
<legend>Parameter Settings</legend>
<table border="1">
$sql = "SELECT PCODE FROM parameter_settings ORDER BY PCODE ASC";
$result = mysql_query($sql, $con);
while ($row = mysql_fetch_assoc($result)){
echo "<tr>
        <td><input type = 'text' name = 'max_pcode' size = '10'></td>
        <td><input type = 'text' name = 'min_pcode' size = '10'></td>

I have table : parameter settings and i have fields: PCODE, max, min

PCODE has data:


I just want to know how can I auto calculate the total max and total min and it will display in the textbox beside Total…

Thank you

When any of the fields that affect the total are update, that is when you would trigger a function that adds up all of the appropriate fields and updates the total value.

Are you looking to create this yourself with some minor assistance from us to help you get on your way, or are you looking for someone to craft together a complete solution for you?

I need minor assistance because its new for me this kind of scenarion and I don’t know if my logic is possible or should I seaprate the total fields in to different table?

Thank you

While you can make use of that PHP and Database code above, it’s next to useless for the rest of us.
Would you mind providing us instead with the HTML code that is rendered to the page itself, or link us to a web page showing what it does?
