How to customize list box to display latest 3 quarters

[ramanarayan]

Attached is a sample qlikview document. We need to be able to customize the Qtr list box to be able to show the latest 3 quarters. The data will keep appending and at all the time this list box should only show the latest 3 quarters.

Thanks,

Ram

One list box expression could be like:

=Aggr(If(Rank(SubField(Qtr, '-',2)&SubField(Qtr, '-',1))<4, Qtr), Qtr)

can this expression be slightly altered to display the selected quarter + 2 previous quarters?
