Multiplication of two calculated measures & wrong subtotals

[FAA9]

hi,

I am struggling to find the right measure for calculating the subtotal at the month level for the Weighted (WTD) stock cover in weeks.
Example of row-wise calculation: (12%+27%)*7.6 = 3.0 of wtd stock cover in wks for Partner A.

In the month total I want to sum up all these results from sub-category and regional level for each Partner to get the sum shown on extreme right. 

Whats the best way to get that? I have tried sumx and summarize etc. Nothing is working 😞
____
Wtd Forecast =
VAR monthly_fc = CALCULATE(Sum[FC Value]), ALLSELECTED(Product[code]), all(Product[Partner]), all(tblDate[Date]) )
VAR weekly_fc = CALCULATE(Sum[FC Value]), ALLSELECTED(Product[code]))

Return
DIVIDE(weekly_fc, monthly_fc)

____
wtd cover= CALCULATE([Days Covers]/7)*(CALCULATE([Wtd Forecast], ALL(Products[Partners]) ) )
