session var is setting ONLY AFTER I reload page, form var displays first page load

[NotGiven]

Page1 has a form that calls Page2. The beginning of Page2:
<? php session_start() ;
$s=$_POST['sSelected'];
session_registe r("s"); ?>

in the middle of Page2 I have a form varaible:
<?php echo $_POST['stateSelected']; ?>
<?php echo $_SESSION['s']; ?>

The form var displays the first time the page loads. The session var
displays only after reloading the page2.

Why?

because that's how HTTP works... read and learn.

w3c is a good starting place, although i seem to remember that the
php.net documentation regarding cookies and/or sessions might give you
a good insight into this.

simple solution to your problem: call session_start() in Page1

Don't use session_registe r with _SESSION (see the manual), fix your code
($_SESSION['s']=...) and your problem will vanish.
