If don't mind trying something new, I'd recommend using entity_metadata_wrapper from the entity API.

Here's a specific example using field collections and a more general example. I've found entity_metadata_wrapper to be much easier than dealing with $node->field_foo[LANGUAGE_NONE][0]['value'] all over the place. Place a dependency on entity in your .info file and have fun.

Here's some code I use for dealing with collections. Perhaps it will help you to solve you problem.

  $collection = field_get_items($entity_type, $entity, 'field_consultant_cost_breakout');
  $count = count($collection);

  $total = 0;
  for ($i = 0; $i < $count; ++$i) {
    // Entity_load will return an array with the entity number as the key.
    $item = array_pop(entity_load('field_collection_item', array($entity->field_consultant_cost_breakout[LANGUAGE_NONE][$i]['value'])));
    $total += $item->field_total_cost[LANGUAGE_NONE][0]['value'];
  }

Subject: [support] Accessing values in the $node variable..

Probably a simple syntax question but as a non-programmer I am battling with it..

I have created an "Invoice" content type that uses an entity reference to a "Patient" content type and within that there is a field collection for addresses.. I am trying to get the address in the first item in the field collection..

My guess is that I have to use something like "entity_load" which I will have to work out when I get there but at the moment I can't work out the syntax for accessing the field collection ID so I can try and load the data for the field collection..
