I'm middle-aged and new to PHP coding which is fun. Here's what I'm having some problem with:

When registering at www.aslexpo.com/info/registration and previewing at www.aslexpo.com/info/preview.php, I see the echo posts there and then hit the "Ticket Request" button to the last page www.aslexpo.com/info/completed.php for printing the pass. The echo posts aren't there.

Is there something amiss?
