debugging this code, should be simple

Hey - could some please help me debug this piece of code...

Here's the error but I can't work out exactly where it is.... Parse error: syntax error, unexpected '>'

<?php

$authors = $wpdb->get_results("SELECT ID, display_name from $wpdb->users " . ($exclude_admin ? "WHERE user_login <> 'admin' " : '') . "ORDER BY display_name");

$author_count = array();

echo "<ul>";
foreach ( (array) $authors as $author ) {
		$author = get_userdata( $author->ID );
		$posts = (isset($author_count[$author->ID])) ? $author_count[$author->ID] : 0;
		$name = $author->display_name;

echo "<a href='/author/" . $author->user_login . "/" . "'>;

echo "<li>" . userphoto_thumbnail($author->ID, ' ', ' ', array(style => 'border:0')) . " " . $user->display_name . "</li>"; 

echo $author->display_name;
echo "</a>";
}
echo "</ul>";
?>

PHP:

 

echo "<a href='/author/" . $author->user_login . "/" . "'>;

PHP:

You're missing a double quote off the end.

 

Oh yeah! Thanks!
