Thanks 🙂
I had some success using your solution. The 2 Arcade expressions seem to work OK, example is the first expression
I then appended my Pop-up URL with ?center={expression/expr0},{expression/expr1}
When opening in Survey123 the behavior is a bit odd as it seems to have appended an entry with ?center
I perhaps should have said that my pop already contains
?field:site_id={SITE_ID}&field:site_name={SITE_NAME}
appended to the URL so that the Site ID and Site Name pre-populates saving the person doing the survey entering it.
So the end of my URL looks like
?field:site_id={SITE_ID}&field:site_name={SITE_NAME}?center={expression/expr0},{expression/expr1}
The red dot on the map in Survey123 Data tab still shows in the Atlantic 😞
Thanks
