Thanks for your response. I just uninstalled the Form Builder 2.0.0 and downloaded the Support Release 2.0.1. - deleted all checkout pages and run the checkout wizard again.
(I noticed your response to another post - so tried this right away)
Unfortunately with the same results and same error message:
Parse error: syntax error, unexpected '?' in /home/anderjoe/public_html/confirm.php on line 466
I also noticed (as the guy in the other post) that the extension manager noted version 2.0.0 after I installed the new support issue 2.0.1 - don't know whether this has something to do with it).
