 * Hi
 * I can’t figure out to to work with the custom fields. I got a feed for a custom
   post type at [http://www.salzburgresearch.at/feed/?post_type=event](http://www.salzburgresearch.at/feed/?post_type=event)
   including a custom field named eventDate.
 * Now in FeedWordPress in the Custom Post Settings I have:
    Key: pubDate Value:
   $(pubDate) and when I try the “test expresssion” I just get then following message:
 * There was a problem communicating with the server.
    result = [object Object]
 * Any help would be great
    Thanks Werner

 * The answer of “MikeSchinkel” works for me.

 * In my view this only answers the question on how to add a custom field to the
   rss feed. I also have the same problem as Werner. My custom fields are visible
   in the rss feed as followed:
 *     ```
       <eventDateStart>25 december 2016</eventDateStart>
       <eventDateEnd>- 26 december 2016</eventDateEnd>
       ```
   
 * But when I try to test the expression I get the same error. Don’t know what I
   am doing wrong here.
 * the Keys are `agenda_start_datum` and `agenda_eind_datum` (as they represent 
   the ACF fields) and the values are set to `$(eventDateStart)` and `$(eventDateEnd)`.
