I am creating a dashboard on ARCGIS Online and am wanting to add an indicator. The indicator I want to create requires me to create a new data expression. I want it to show the Call Percentage, which would be the total count of the "Code" field/ total count of the "Dispositions" field. The majority of the data in the dispositions field is empty if that helps. I figured out how to run it and get the correct output, but whenever I press Done it says that "Unable to execute Arcade script". It looks like I need to return a FeatureSet instead of text, but I run into even more problems when I try to return a FeatureSet it says"error: Execution error - Cannot access value using a key of this type. Verify test data". Can anyone help me with this?
