  (Asked by: username_0 on 2017-08-30)
  
  I have "locations" section where each entry is a location, with a Smart Map field for the address.
  
  I have another section "pages", where I have a matrix field which contains an entry relationship field, where I can select entries (locations) from the first channel.
  
  I'm trying to output a map of all locations selected in my matrix field, but I'm getting an error:
  Property "Craft\SmartMap\_AddressModel.title" is not defined.
  
  I'm using the code below to get the address fields from the individual entries, and put them into an array. I think maybe I'm not understanding what exactly needs to be in the locations array:
  
  ```
  {% set locations = [] %}
  
  {#  loop though all relationship fields for this entry #}
  {% for block in entry.pageBuilder.type('listingGroup') %}
  
      {#  loop through related entries #}
      {% for member in block.listing %}

  At a glance, your code *looks* perfect... but I think there's a subtle error. The `locations` parameter can be an array of **elements**, but you are building an array of **Address fields** (which is not valid).

  [![locations](https://i.sstatic.net/GFUYT.png)](https://i.sstatic.net/GFUYT.png)
  
  You can simplify the middle part of your code to this:
  
  ```
  {# add entry to locations array #}
  {% set locations = locations|merge([member]) %}
  
  ```
  
  That way, `locations` will end up being **an array of elements**.
