Good afternoon,
I created two variables on my qlik app, one that identifies the current month, and one that identifies the previous month. Now I wish to calculate the difference in detections between each month, I was trying to use the following expression but got an error:
=Sum({<'$(=vCurrentYearMonth)'>} Detections) - Sum({<'$(=vPreviousMaxMonth)'>} Detections)
Any suggestions?
Detections is a defined measure in my app.
