Note that vbsetcookie() will add your cookie prefix to the cookie, so it actually should be:

PHP Code:

if (!isset($_COOKIE[COOKIE_PREFIX . 'GeoIP']))
{
   // put geo locating code here
   include('./geoip.php');
   $countryCode = getCountryCode($_SERVER['REMOTE_ADDR']);

   // set cookie
   vbsetcookie('GeoIP', $countryCode, permanent);
}
else
{
   $countryCode = $_COOKIE[COOKIE_PREFIX . 'GeoIP'];
}
