I did as you said Richard, however I still encounter the same problem,
you can take a look at the code in test.txt, I updated it too.
For other people, here is the original message:
Hello,
I got this example of sessions: www.net.co.cr/test/test.php ,
however, as you can see in the code at /test/text.txt , isnt $_SESSION
['tree'] suppose to contain a value and not be NULL?
Thanks.
