Reply To: Querying with ACF relationship values

Hey John, Thank you for the quick response. I tried implementing the solution you suggested but have some sort of PHP error because I am getting a white screen on page load. Yes, I am trying to display the div tout-more-specialists and all of its content if the div has a relationship with more doctors.

For Example:

The Doctor has a specialty of Urology. I only need to show the div tout-more-specialists if there are other specialists that also specialize in Urology. If there are no other doctors specializing in Urology then display an alternate div with alternate content. I successfully was able to use the relationship fields to get all doctors that have the same specialty, but my issue is setting it up where if no one else has that specialty then display other content. Again any help is appreciated and thank you for getting back to me.

Here is my updated code based on your suggestion. (The reason I am posting all of the code on the page is because I am not sure if it is causing other conflicts.)

<?php get_header(); ?>
