Thank you Redirect GET issues

[nativeindustries]

I have been searching find any documentation on this. I want to redirect my purchasers to a thank you page on our website. Usign the GET method I want to be able to display their name, txn id etc. When I test this with a product with no price no info appears where it should.



A Snippet of the code on the thank you page looks like this



Thank you <?php echo $GET['firstname']; ?><br>

<br>

Your order using the following email address <?php echo $GET['payeremail']; ?> will now be



Any ideas what I might be doing wrong?

If you could, please post the Buy Now button code we provide for this test product; then we can test it ourselves and see what it triggers on our back end, just in case there's a bug we might need to fix.
