ArcGIS Online duplicate value Arcade Expression

PeteCoventry5

I'm needing some help with an Arcade Expression for ArcGIS Online.  I need to symbolize any duplicate value in red and the remaining unique values in green.  I understand that I could create a new field any identify these duplicate values, but trying to resolve this with an Arcade Expression.

Hi,

I'm not sure if this is possible because the Visualization profile doesn't expose the layer as a profile variable, only the current feature and it does not include the Data Access bundle. https://developers.arcgis.com/arcade/profiles/visualization/

It looks like you could provide this info in a popup using

var rec_count = Count(Filter($layer, "FIELD_NAME='"+$feature.FIELD_NAME+"'"))
return IIf(rec_count>1, true, false)

If your data is relatively static, I would store this info in a new field.
