Outputting Select Sum

[eluser]tecrik[/eluser]
No kidding, I am having a blast Thanks so much for the help here, though!

So I ran into a different problem with this part:

Code:

function order_value_average ()
{
  $this->db->select_avg('summe');
  $query = $this->db->get('orders');

  return $query->summe;
            
}

According to the user guide, this part

Code:

$this->db->select_avg('summe');
$query = $this->db->get('orders');

should produce something like "SELECT AVG(summe) as summe FROM members" which makes the entire snippit very similar to the one in my inital post. Still, I get the following error message "Undefined property: CI_DB_mysql_result::$summe" in my view.

In general, I am confused about the "return" part, meaning how to return data and in which way. Is there some kind of documentation for that?
