I've tried playing with the $_SERVER['HTTP_REFERER'] and that's no good
because it's all coming from the same page - index.php!!
What am I missing. . . ?

Hi Kristen, there's a misunderstanding:

The code below isn't much help to debug. Do some checking to figure
out how far into your IF statement you're getting. Is the query
running?
Yes it runs successfully
Is it the query you expect?
Yes it is perfect, and provided this is a new session and we're going
forward page by page, it properly deletes from and inserts to the db as
expected
(Step #1 when inserting or creating dynamic
queries that aren't working: print them out to make sure they are what
you think they are.) Is the category being incremented?
Yes, absolutely
You say you can go back, but you can't go forward.
Actually no. In a new session, I can start and go forward page by page
to the end of the questionnaire, advancing each stage perfectly, storing
all values exactly as I'd expect.
The trouble starts if, during the process, the user hits the BACK
button. At that point, user can reload the last page of questions,
displaying the answers they gave. If the user makes changes, those
changes get error checked but do not become part of the sql query. Also,
user can not move forwards any more. So it's as the subject says -
everything works...until they hit the back button, from which point the
whole thing goes gablooey.
Look at the page source, is the
form action what it should be?
Yes
Look at the form hidden variables (if
any) are they what you expect?
No. $cat remains what it was BEFORE the user hit the BACK button.
However the questions dispayed are from the $cat which is in fact $cat-1
