Calculating variation of a value between current and previous month
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.
