A little background information:
this is the fourth part of a comment form on my site... This is the part where the comment gets validated and that the user gets the option of edditing it or posting it. I am having slight problems though... I get:

Notice: Undefined variable: _SESSION in C:\netserver\www\Pureadd\pictures\comment\1c.php on line 8

Notice: Undefined variable: _SESSION in C:\netserver\www\Pureadd\pictures\comment\1c.php on line 9

Notice: Undefined variable: _SESSION in C:\netserver\www\Pureadd\pictures\comment\1c.php on line 10

Notice: Undefined variable: _SESSION in C:\netserver\www\Pureadd\pictures\comment\1c.php on line 11
Here is the code for that page:

<?php
$username = $_SESSION['Username']; // Line 8
$password = $_SESSION['Password']; // Line 9
$email = $_SESSION['Email']; // Line 10
$ID = $_SESSION['ID']; // Line 11
$rating = $_POST['rating'];
$comment = strip_tags($_POST['Comment']);
$lcomment = strlen($comment);
if($lcomment<=400 && $lcomment>=3){
$correct = 0;
$correct++;
}else{
$correct = $correct*0;
}
if($rating<=5 && $rating>=0){
$correct++;
}else{
$correct = $correct*0;
}
$time = date('h:i:s A');
$date = date('m/d/Y');

Either I don't think I set the Session variables correctly because i just do this to set the Session variables:

$_SESSION['Username'] = $_POST['username'];
It was working before I re-did the code to fix the ad link problem... *Not evident on this page...*

Your can set them like that. Only problem is you forgot the most important rule when using sessions, the first line of php should have:
session_start();

Thats already there on 1.php *the first of six pages linked in this session...* and when I do put that on any other pages... the browser's php interpretor flips out and can't handle it and throws this on the page:

Could it be that the selected lines of code Line 8-11 need to be in the body? I tried it and it doesn't work... I'll get that error line in a minute...

Either the computer hates me or I haven't registered the Session variables correctly...
Thanks

I see nothing in any of the pages you pointed to above that has the code to begin the session:



<?php
session_start();
?>


should be placed at the very beginning of the php pages.

Hope this helps.
