// This prepares e-mails for filtering
if($options['filterEmail'] != "") {
	$filterEmail = trim($options['filterEmail']);
	$filterEmail = explode(",", $filterEmail);
	for($i=0; $i<count($filterUrl); $i++) {
		$new_emails .= " AND comment_author_email NOT LIKE '%" . trim($filterEmail[$i]) . "%'";
	}
	$filterEmail = $new_emails;
}

this does not work
for($i=0; $i<count($filterUrl); $i++) {

for($i=0; $i<count($filterEmail); $i++) {
