Hi there, make sure you aren't outputting anything to the browser prior to
sending headers ie the echos on top of page 3. When you register a session
variable you should assign it a value ie:
session_register("mysessionvar");
$mysessionvar = $whateveryouwish;
Also make sure session_start(); is at the top of every page with no space
before.
These should help you out a little. Joe :)
