easy php snippets

Hello,

I just installed the module ip2nation, ( http://drupal.org/project/ip2nation ) but I can not find the snippet to display the flag of the commentators except in the $links.
I want to display the flag in the top of comments or leftside under the user picture can you help please ?

I try the snippet

print theme('('ip2nation_flag', $comment'))),

but it does not work.

This is the module code

 * @param $ip the IPv4 address, which is in the format equivalent to that of $_SERVER['REMOTE_ADDR']
 */
function ip2nation_get($ip = NULL) {
  static $cache = array();
  if ($ip === NULL) {
    $ip = ip_address();
  }

		return new stdClass();
	}

			$sql = "SELECT c.code, c.country ";
			$sql .= "FROM {ip2nationCountries} c ";
			$sql .= "INNER JOIN {ip2nation} i ON c.code = i.country ";
			$sql .= "WHERE i.ip < INET_ATON('%s') ";
			$sql .= "ORDER BY i.ip DESC ";
			$sql .= "LIMIT 0,1";

			$cache["$ip"] = db_fetch_object(db_query($sql, $ip));
		}


  return $cache["$ip"];
