I’m trying to replicate the “Conditional Field Display” as wonderfully noted by Kelly Gerrow et al, https://community.esri.com/community/gis/web-gis/arcgisonline/blog/2017/07/18/conditional-field-display-with-arcade-in-pop-ups with my particular dataset, but running into an issue – possibly with the field name??

Here are the steps I’ve taken:

Step 1. Create an Arcade Expression

IIF (isEmpty($feature[“Apt_link”]),””,”Description”)

(Instead of $feature.description format specified in the instructions, I'm using [" "]...could this be the problem??)

Step 2. Configure Customer Attribute Display

{ownername1

{expression/expr0}  {Description}

Both the expression/expr0 and Description are lined to the "Apt_link" field in my dataset.  

Here's a link to my webmap:

Any help would be greatly appreciated!!
