[paulyeo11]

Hi All

Chart A Expression is not SET analysis ( working fine ) :-

money(

fabs(

sum(Amount/$(Columndim89))/1000)

, $(vCurrencyFormatK))

I convert the chart A to Chart B the Expression is  using SET :-

sum({$<year = {"<=$(=max(year)) >=$(=max(year)-12)"}, month = {"<=$(=max({<year={$(=max(year))}>} month))"}>}

Amount/$(Columndim89))

My issue is for Chart B only display jan till march 2013.
