Calculate Variance Dynamically Across 2 Matrices

I feel like the solution should be very simple but I'm stumped. Any help please?

 

I have two matrices (A and B). Each matrix has its own date filter/selection. Through interactions, I've managed to assign seperate date filters to each matrices. Depending on the dates selected, I want to calculate the variance between Matrix A and Matrix B.

In the diagram below, Matrix A is set for Qtr 4 2021 (this matrix will always show 1 date). Matrix B is selected for Qtr 1 and Qtr 2 of 2022 (this matrix will show one or more dates). I am having difficult calculating the variance in Matrix B. Because I've turned off interactions, I can't get SELECTEDVALUE to work in my measures.

Can I get some help please? Thank you 🙂

@TH_BI , You can try a measure below for variance

 

new measure =
var _max1 = maxx(allselected(Date),Date[Date])
var _min1 = minx(allselected(Date),Date[Date])
var _max2 = eomonth(_max1,2)

var _min = eomonth(_max1,-1* if( mod(Month(_max1),3) =0,3,mod(Month(_max1),3)))+1
var _max= eomonth(_min, 2)
return
if('Date'[Date]>= _min && 'Date'[Date] <= _max , "Latest Qtr" format([Date], "YYYY-QQ") )

return
calculate( sum(Table[Value]), filter('Table', 'Table'[Date] >=_min && 'Table'[Date] <=_max)) - calculate( sum(Table[Value]), filter('Table', 'Table'[Date] >=_min1 && 'Table'[Date] <=_max2))

Thanks Amit! I'll give it a try.
