what exactly is wrong with this?

parse error, unexpected '{' on line 5

[mylungsarempty]

<?

session_start();

if((!$_SESSION[username]) && (isset($_POST[username])) && (isset($_POST[password])) {

$username = $_POST[username];
$userpass = $_POST[userpass];

$_SESSION[username] = $username;
$_SESSION[userpass] = $userpass;

} else {

$username = $_SESSION[username];
$userpass = $_SESSION[userpass];

}

?>

...why is the bracket "unexpected"?

<?
session_start();

if((!$_SESSION['username']) && (isset($_POST['username']) && isset($_POST['password'])) {

You seem to be missing a closing bracket in the second part of this statement; maybe try changing to this:

if((!$_SESSION['username']) && (isset($_POST['username'])) && (isset($_POST['password']))) {

ahhhhhh thankyou so much -- PHP can be so frustrating when you're a novice.

A simple trick is to count along the backets rather than trying to match them all up, adding one for a left bracket, and subtracting one for a right, then if you don't end with zero, you've missed bracket somewhere

if((!$_SESSION['username']) && (isset($_POST['username']) && isset($_POST['password'])) 
 1 2 .................... 1 .. 2 ... 3 ................ 2 ....... 3 ................ 2 1
