I got strange behaviour of QV and hope someone can help/explain.
I got 3 variables and 2 trigger action on varaible change to limit numer of selection in list box. The max allowed selections are 2 and whenever 3rd selection is made it is deselected.
When I had text box to display the variables all was working fine. Once I removed it, the 3rd value was kept.
I opened window with variable the check the one which is set after other is set and it was ok. After the lookup it was working again. I did Clear All and was not working.
Only when variable is displayed and checked it behave as it should.
I have attache the example when you can do 2 selection on the listbox on top right.
If you remove blue text box -> do Clear All -> save, you can select more than 2 options.

edit to add: I'm getting know aggr now and =if(GetSelectedCount(ProjectName)=2,aggr(ProjectName,ProjectName),ProjectName) in list box is doing great! job, however question about when above variables work correctly stays open.
