retrieve for data

Hi Experts

The below code takes the results of a form and saves it to a mysql database. Im pretty new to PHP and have used tutorials to create the below code. Save to mysql works fine but when I try to constuct a sting it fails on line 30

$part2 = echo $_POST["firstname"];

Im trying to retrieve the fistname field of the form.

Hows do I do this please.

Many Thanks

Lee


<?php
$con = mysql_connect("localhost","web17-ebayorder","testtest");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }

mysql_select_db("web17-ebayorder", $con);

$sql="INSERT INTO test
(firstname,lastname,address_line_1,address_line_2,town,county,postcode,domain_name,email,code)
VALUES
('$_POST[firstname]','$_POST[lastname]','$_POST[address_line_1]','$_POST[address_line_2]','$_POST[town]','$_POST[county]','$_POST[postcode]','$_POST[domain_name]','$_POST[email]','$_POST[code]')";

if (!mysql_query($sql,$con))
  {
  die('Error: ' . mysql_error());
  }

//echo "Success!";
?>
