Thanks for your reply. Let me be more precise; the end result should dynamically show the % - change between the current and previous month, preferably in a KPI text-box. Ex. When the user selects 201403, the % change from 201402 should automaticcaly appear. That’s why I'm interested in getting the set-analysis above to work.
Any input on how to solve this? I’m really struggling to see why the set analysis does not work properly.
