actions block

Ive been trying to get the actions block to show but i couldn't. So i looked in the code:

function theme_user_relationship_block_actions($account, $block_type, $rtype, $extra) {
  if (!$account) { return; }

  global $user;
  $viewer =& $user;

  $output = array();
  if ($viewer != $account && $list = _user_relationships_between($viewer, $account)) {
    $output[] = theme('item_list', $list, t('Your relationships to this user'), 'ul', array('class' => 'user_relationships'));
  }

  if ($actions = _user_relationships_actions_between($viewer, $account)) {
    $output[] = theme('item_list', $actions, t('Relationship actions'), 'ul', array('class' => 'user_relationships_actions'));
  }

  return implode('', $output);
}

I noticed that $list isn't being passed into this function and in fact isnt even in the calling function.

please help

thanks
Josh
