OpenInviter.com library wrapper

[eluser]Unknown[/eluser]
i am new to codeigniter. I used this code.But i am getting error. i used 'aol' as plugin name. But its giving error as 'Undefined index: aol'..

Then i entered into the function grab_contacts($plugin,$username,$password) and made a small change which is shown below in order to echo the error.

$this->plugin=new _hosted($plugin_name);
return $this->plugin;
exit();

Now i am getting error as shown below.

_hosted Object ( [login_ok:private] => [showContacts] => 1 [internalError] => [requirement] => [allowed_domains] => [service] => aol [timeout] => 60 [session_id:protected] => [curl:private] => [has_errors:private] => [debug_buffer:private] => Array ( ) [service_user] => [service_password] => [settings] => [messageDelay:private] => [maxMessages:private] => )


Can anybody help me by saying where i went wrong...Please.
