Session variables in PHP

[Anon]

So on my first page I register my sessions

session_register("usernamesess");

after a redirect like this:

header("Location: teamadmin.php");

on the next page I do

session_register("usernamesess");

I get this error

Warning: Cannot send session cache limiter - headers already sent (output started at /home/67-373/team03/public_html/FinalWebsite/teamadmin.php:16) in /home/67-373/team03/public_html/FinalWebsite/teamadmin.php on line 18

what version of php?

you don't need to register the variables twice... once registers it through all your pages and can be accessed as such
