Accumlated Fiscal start to current month Set Analysis

[#1]

hi .

I am trying to create an accumulated value.

I have a fiscal year 2013/2014.

Start Month is May.

I wish to select the fiscal year i.e 2013/2014 and Month Jul and return the values between May - Jul    for 2013/2014.

i have the following statement but it is not working currently.

Any help greatly appreciated.

Sum(

        {$< FYear={"$(=Dual(Max(fYear)-1 & '/' & Max(fYear), Max(fYear)))"}>}

            FMonth={"<=$(==Max( {<fYear={$(=Max(Year))}>} Month))"}   

>

Sum(Amount)

Best
