Title: Relationship through Matrix field
ThreadText: # Relationship through Matrix field
  
  (Asked by: username_0 on 2015-07-23)
  
  I'm having a little trouble wrapping my head around [Relations](http://buildwithcraft.com/docs/relations) through a [Matrix](http://buildwithcraft.com/docs/matrix-fields) field.
  
  I have a [Structure](http://buildwithcraft.com/docs/sections-and-entries#section-types) called `exhibitors`.
  
  I have a Matrix field on a Page called `rooms`, This has one block type `room` and within that block there is an entries relationship field called `exhibitors`.
  
  What I'm wanting to do is loop through the `exhibitor` entries and for each one, I want to find the first room they are related to via the matrix field.
  
  I've tried various flavours of the `relatedTo` method, but I just can't seem to get them related, I just get null back from every one I've tried.
  
  Here's an example of one I've tried:
  
  ```
  {% set exhibitors = craft.entries.section('exhibitors').order('title') %}
  
  {% for exhibitor in exhibitors %}
      {% set room = entry.rooms.relatedTo({
          sourceElement: exhibitor,
          field: 'room.exhibitors'
      }).first() %}
  
  {{ room }} <-- Always a null entry
  
  {% endfor %}
  
  ```
