Attribute Expression - remove null value

PeteCoventry1 — Tue, 15 May 2018 14:23:43 GMT

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!!

Hi Pete,

What would you like the pop up to display? Do you want to display the value in a field or label a field?

Hi Kelly!

I'd like the popup to display "Apartment Link" only when the url is available. "Apartment Link" would obviously be linked to the URL in my attribute table.

Thanks!!

Pete

Turns out that I had a space (" ") in my records causing the expression not to work correctly.

Thanks to Kelly for all her help!!
