ADD_ACTION to an External URL and passing values

I am fairly new to Grocery Crud and I have read the documentation and searched the forum but I am looking to see how I can add an External URL instead of a link to another crud model within my application. Here is my example:

public function participant()

{

$crud = new grocery_CRUD();

$crud->set_theme('datatables');

$crud->set_table('participant');

$crud->where('participant.EVENT_ID',1011);

$crud->display_as('EVENT_ID','Event');

$crud->display_as('DIVISION_ID','Division');

$crud->set_relation('DIVISION_ID','division','{DIVISION_NAME}');

$crud->set_relation('EVENT_ID','event','{EVENT_NAME}');

$crud->add_action('Score', '', 'demo/action_more','ui-icon-plus',array($this,'score_participant'));

}

public function score_participant($primary_key , $row)

{

return redirect("http://www.example.com/add_score.php");

}

When the PARTICIPANT model renders it wants to immediately redirect to my redirect page. I want to be a link that is external that I will eventually pass the row parameters to a custom external php page. I have also tried to use SITE_URL, but that doesn't work cause it tries to build the base url for grocery crud with expecting it to go through the controllers. Can someone give me a tip on how to make it go to a custom non grocery crud link and pass some values of the row to it?

Here is a screen shot of my example.
