Hi...
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:

Code:
<html>
<head>
<style type="text/css">
#fieldset_PS{
    position: relative;
    width: 20%;
}
</style>
<link rel="stylesheet" type="text/css" href="kanban.css" /> 
<script type="text/javascript">
  
function display_PS(){
    document.loading_kanban.action="ParameterSettings.php";
    document.loading_kanban.submit();
}
function display_Kanban(){
    document.loading_kanban.action="kanban_report.php";
    document.loading_kanban.submit();
}
</script>
</head>
 <?php
  error_reporting(0);
$con = mysql_connect('localhost', 'root','');

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

mysql_select_db("mes", $con);



?>
<form name="loading_kanban">
<div id="main_button">
<center>
<!--<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>
<div id="fieldset_PS">
<fieldset>
<legend>Parameter Settings</legend>
</center>  
<table border="1">
<th>Compounds</th>
<th>Max</th>
<th>Min</th>
<?php
$sql = "SELECT PCODE FROM parameter_settings ORDER BY PCODE ASC";
$result = mysql_query($sql, $con);
while ($row = mysql_fetch_assoc($result)){
echo "<tr>
        <td>$row[PCODE]</td>
        <td><input type = 'text' name = 'max_pcode' size = '10'></td>
        <td><input type = 'text' name = 'min_pcode' size = '10'></td>
        </tr>";
}   
?>
</fieldset>
</table>
</div>
</form>
</html>
I have table : parameter settings and i have fields: PCODE, max, min

PCODE has data:

PXX
PYY
PZZ
PAA
PBB
Total

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
