Previous Month for Current Year

[scotly-victor]

I wanted to show 2 line chart

1.current year current month

2.current year previous month.

Dimension:Month

My current Year current month expression is

sum({<type={'Order'},FiscalYear={$(=max(FiscalYear))}>} Sales) (works fine)

My current Year previous month expression is

=(above(Sum({<type={'Order'},FiscalYear={$(=max(FiscalYear))}>}Sales ))) (issue)

If I use above expression till may (right to left) I am getting precise value ,however  apr is null,

Can any one help me?
