argh! hotmail sucks
I don't see in the script where you are using $_POST / $_GET / $_REQUEST to access tha data from the form. Its likely that the example you are following is old and uses 'register_globals'. Since register_globals is a huge security hole and is not active in any new installations of PHP you need to change your script to use the above methods to get the form data. The error you are getting is due to the fact that you are not passing in the values to the sql and not getting a valid result
Note that the below example fixes your issue but DOES NOT do any validation, which you really should do before passing your data to the sql...
$userid=mysql_real_escape_string($_POST['userid']);
$password=mysql_real_escape_string($_POST['password']);
if($rec=mysql_fetch_array(mysql_query("SELECT * FROM tablename WHERE> userName='$userName' AND password = '$password'"))){
if(($rec['userName']==$userName)&&($rec['password']==$password))
