PHP if syntax and syntax error. [duplicate]

I get "syntax error, unexpected end of file." I'm probably not using the if on line 7 correctly. If I remove line 7 8 and 9 I don't have an error. `It is like I'm missing a { or } somewhere there. Does the if have to be on it's own PHP line ? Thanks

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST') {     
    if (!empty($_POST['LicenceNo']) && $_SESSION['MEMID'] == '')  {
        require ('sql_get_MNZID.php');                       
    }else { 
        if(isset($_SESSION['Password']) && isset($_POST['Password'])){                
            if ($_SESSION['Password'] == $_POST['Password']):?>
                <a href="index_login.php">New Page</a>    
            <?php endif; ?>   
        }
    }
}else{
    $_SESSION['MEMID'] = '';
    $_SESSION['Password'] = '';   
    $_SESSION['MemName'] = '';
}    
?>
