Drupal 7 contexual filter display block based on node reference I have been going around in circles with this for a few hours now... Time to ask for help!!

I have two Content Types:

1: Book

2: Reader

The Book Content Type has a node reference field which is a select list of readers create with the Reader Content Type.

This is all set up and working fine.

Now the issue with my views:

I have a view with is a block containing the Reader fields. What I want to do is have it when the Book node is loaded my block shows underneath with the referenced reader details. Also if no reader is referenced then no block shows up.

I have spent some time in Relationship and Contextual Filters but can't get it to work.

The book URL is formatted like this:

books/[book-title]

I tired using 'raw value from url' in Contextual Filters as setting it to the 2nd argument but that didn't work either.

If anyone can help me out here I would be very much appreciative.

Thanks

Create a simple content view of readers add fields and add a contextual filter of field_book or whatever is the name of reference field and choose option "When the filter value is NOT in the URL" -> "Provide default value" -> "Content ID from URL" and save.
