What's wrong?

<?php
include('config.php);
if(isset($_COOKIE['BSComputersU']) && isset($_COOKIE['BSComputersP'])){
    $username=$_COOKIE['BSComputersU'];
    $query = mysql_query("SELECT username,password FROM users WHERE username = '$username'") or die(mysql_error());
    $data = mysql_fetch_array($query);
    $password=$_COOKIE['BSComputersP'];
    if($data['password'] != ($password)) {
        header("Location: index.php");
        }
    else{
    if(!isset($_COOKIE['BSComputersU']) && !isset($_COOKIE['BSComputersP'])){
    header("Location: index.php");
        }
    else{
    $query = mysql_query("SELECT username,password FROM users WHERE username = '$username'") or die(mysql_error());

    $_SESSION["s_username"] = $row['username'];
    header("Location: index.php"); 
    }
}
?>

I get a parse error on line 3

include('config.php');

The syntax highlighting should show you that

[sveegaard]

DOOH! Thnx....but now there's a parse error on line 22...

You're missing a closing brace.

Use consistent indenting, then you will not miss these things

I went through all the code for you.

<?php
  include('config.php');
  
  if (isset($_COOKIE['BSComputersU']) && isset($_COOKIE['BSComputersP'])) {
    $username = $_COOKIE['BSComputersU'];
    $query = mysql_query(
      'SELECT username,password '.
      'FROM users WHERE username = \''.$username.'\''
    );
    if (mysql_errno())
      echo mysql_error();
    
    $data = mysql_fetch_array($query);
    $password = $_COOKIE['BSComputersP'];
    
    if ($data['password'] != $password) {
      header('Location: index.php');
    }
    else if(!isset($_COOKIE['BSComputersU']) && !isset($_COOKIE['BSComputersP'])){
      header('Location: index.php');
    }
    else {
      $query = mysql_query(
        'SELECT username,password '.
        'FROM users WHERE username = \''.$username.'\''
      );
      if (mysql_errno())
        echo mysql_error();
      
      $row = mysql_fetch_array($query);
      $_SESSION['s_username'] = $row['username'];
      header('Location: index.php');
    }
  }
?>
