Hi there :)

It all depends... If you're on a next/different page then where
you've 'started' the session-vars you first have to call
session_start(). After that you can either do:

  print ($varname);
or (better):
  print ($HTTP_SESSION_VARS["varname"]);

If you're still on the same page as where you 'start' the
session-vars, there are two ways:

First register the variables (otherwise they're not session-vars),
and then you can print them in two ways:

  session_register ("varname");

and then:
  print ($varname);
or (better):
  print ($HTTP_SESSION_VARS["varname"]);

The other way is (when you're still on the same page) to not use
them as session-vars at all (ofcourse depending on what you want to
do with 'm). Then they're still just normal vars ;) :

  print ($varname);

If you want to check which session-vars you have available do:

  print_r ($HTTP_SESSION_VARS);
or (more info):
  var_dump ($HTTP_SESSION_VARS);

Ofcourse you need to call session_start() before this...
