Cumulative Profit in a year using a parameter.

[ruthhacche]

I have a parameter to select my current Fiscal Year,

Profit Selected FY = calculate([Profit], filter( 'Calendar','Calendar'[FiscalYear]='Parameter This FY'[Parameter This FY Value]) ) works
Profit Selected Last FY = calculate([Profit], filter( 'Calendar','Calendar'[FiscalYear]='Parameter This FY'[Parameter This FY Value]-1) ) works

cumulative works for this year

Profit Cumulative FY Selected = CALCULATE(
[Profit Selected FY],
filter(
aLL('Calendar'[Date]),
'Calendar'[Date]<= MAX('Calendar'[Date])
)
)

But I cannot do that for the previous year - This does not work. How do I get this one to look back 12 months?

Profit Cumulative Previous FY Selected = CALCULATE(
[Profit Selected Last FY],
filter(
aLL('Calendar'[Date]),
'Calendar'[Date]<= MAX('Calendar'[Date])
)
)
