Sessions problem

[calavera]

I'm new to sessions, and I'm just trying the most basic script for now:

<?php

// if a session does not yet exist for this user, start one
$id2=session_id();
if ($id2==false){
echo "session did not exist \n";
session_start();
session_register('count');


}
else { $id2=session_id(); session_start($id2); }

// increment count
$count++;
echo "You have been here $count times";

?>
It's a bit messy, but that's what happens when trying to fix problems.
ANyway, the error I keep on getting is this:

Warning: Cannot send session cookie - headers already sent by (output started at /home2/sserver/public_html/menu.txt:2) in /home2/sserver/public_html/menu.txt on line 8

Warning: Cannot send session cache limiter - headers already sent (output started at /home2/sserver/public_html/menu.txt:2) in /home2/sserver/public_html/menu.txt on line 8

Anyone have any idea what I may be doing wrong?
Thanks in advance to all who help,
Manuel

First, you don't have to specify the session ID.

just put "session_start()" at the top of every page and make sure that PHPSESSID is sent to each page either through cookies or the URL.
That's all you need.

Second, the error you get is because somewhere in the script you are printing something before you use the 'session_start()' command.
It's either a print or echo command, or there is an empty line somewhere outside the <? ?> tags.
