Hi..

I have forms and I only need to input is the Demanded Qty, and from Demanded Qty that I input it will compute the demanded qty for each Item Code.

Now my problem is I don't know on how can it possible that while i input the quantity it will also autodisplay the demanded qty for each materials.

Noted: the Demanded Qty that will auto display is display only on the Demanded Qty you input per Items.
For Example:

On Item = P28 i input demanded qty, only on the ItemCode will display the output.

and when i input on P30 the computation will display on the ItemCode for P30.

here is my code:



<?php
error_reporting(0);
date_default_timezone_set("Asia/Singapore"); //set the time zone
$con = mysql_connect('localhost', 'root','');

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

mysql_select_db("mes", $con);
?>

function compute_quantity(){
var DemandedQty = document.getElementById('DemandedQty').value;
var Quantity = document.getElementById('Quantity').value;

var SubQty = (DemandedQty * Quantity);
}
</script>

$DemandedQty = $_POST['DemandedQty'];

$sql = "SELECT DISTINCT Items FROM bom_subitems ORDER BY Items";
$res_bom = mysql_query($sql, $con);

while($row = mysql_fetch_assoc($res_bom)){

$Items = $row['Items'];
$Items_ = substr($Items, 12, 3);

echo "<tr>
