Yes i put this code:

<?php
session_start();
$error = $_SESSION[‘error’];
?>

In the Start of Page section of the errorpage html.

Do you think an error is happening on the Free Report page when the visitor submits their details or that something is wrong with the link to the thank you page, or even that some thing is wrong with the thank you page?

In case you need to see pages:
Free Report page: http://www.swiftsaleproperty.com/freereport.php
should link to Free Report Thankyou page: http://www.swiftsaleproperty.com/frthankyou.php
where you can download a PDF, which works ok.

One thing - i have not created a new errorpage for the Free Report form, i have used the one i already had for the contact form i have on the right hand side of every page - is that the problem? I was guessing that because the action of the Back button on the errorpage always sends a user back to the page they just came from, it would be ok to use the same one for both forms? It's here: http://www.swiftsaleproperty.com/errorpage.php

Talking about this form, the "action" is wrong:

action="dbts_abvfp.php"

Instead of the correct action="http://www.swiftsaleproperty.com/ABVFP/dbts_abvfp.php"

Yes, there is no problem using the same errorpage
