consulting variable

Your original query ($query) most likely failed. Did you supply a valid $email and $pass?

Try this (for testing):

PHP Code:

$query = $this->db->query("select email, country, pass from users where email = '$email' and pass = '$pass'")->result();
if ($query) //test if query was successful
{
  echo 'Country = ' . $query->country;
}
else
{
  echo 'ERROR in Query:<br>' . $this->db->last_query();
}
