Have a close look at the array member above. It's spelled differently from the others
(an
A is missing).

I'm having trouble understanding how your application works. For starters, I don't see
where $POST['sellocation'] is being set, because you didn't provide us with that part
of
the code. It's true that, as it didn't make immediate sense to me, I didn't bother
reading
the code again because I don't have much time.
A couple of things off the top of my head that may or may not be related to your
problem: (a) if you're using any values sent via the URL string (e.g. cf=0), you need
to
use $_GET, not $_POST; (b) empty() will also evaluate to true if the value of the
variable
is zero.
Good luck,
Erik
