OP, please replace this text with a detailed description of your problem. Your code is below.
I used document.getElementById but the math is not working. I need total to be calculated:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title></title>
<script type = "text/javascript">
function a()
{
var q = document.getElementById('ad').value;
document.getElementById('s').value=q + q;
}
</script>
</head>
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("form1", $con);
error_reporting(E_ALL ^ E_NOTICE);
$nam=$_GET['msg'];
$row=mysql_query("select * from inv where Name='$nam'");
while($row1=mysql_fetch_array($row))
{
$Name=$row1['Name'];
