Well... You can't sent any headers after
some output has already
been sent. I didn't take a very good look at your
code, but looking
at the warning you get and the position of
session_start() in your
code, I'd say you have to move the session_start()
up. You can best
start your code with session_start() and then the rest of
your
script.
