User login with Sessions?

[toddg]

--
<?php
Session_start();

// Connects to sql server and logs in with username and password  

$SQL connection  

// Selects all of the data from database 

$sql_text = "SELECT * FROM users WHERE usrName=".$UsrName." AND usrPassword=".$Pswd.";

$query=mysql_query($sql_text) or die (mysql_error ());

$logged_in="no";
session_register("logged_in");

if($mysql_num_rows($query)!=1){
$SESSION["logged_in"]="no";
header("Location: ./sorry.html");
exit();
}
else{
$SESSION["logged_in"]="yes";
_header("Location: ./family/index.html");
_exit();
}

?>

But I keep getting: Parse error: parse error, unexpected T_STRING in ../validate.php on line 15

Can someone help me out with a simple login using sessions?

Thanks!

why you declare your variable as

$logged_in="no";

Why ther is = instead of just '=' ?

Thanks
