Reverse node-reference views argument

Hi.

I am looking for a neat solution for the folowing problem

I have pages. These pages have a node-reference-CCK-field. The reference is to one or more stories. Every refered story should show up in a block.

Well it's a view with a nice argument setting.

I recon that every page should refer to it's "children". Every child should show up in the view.

I thought I could solve it by using code similar to:

View argument at "Provide default argument":

if (arg(0) == 'node' && is_numeric(arg(1))) {
  $node = node_load(arg(1));
  return $node->field_field_story_ref[0]['nid'];
} else {
  return FALSE;
}

I am stuck somehow. Any hints?

Thanks!
