powerbi – Power BI – How to create new column that summarize data by week and by Online or Store Channel?

I have WTDdata table that contains ThisYearRevenue and LastYearRevenue summarized by week:

enter image description here

I need to create 4 more columns LastYearOnlineRevenue, LastYearStoreRevenue, ThisYearOnlineRevenue, and ThisYearStoreRevenue from another table (RevenueByDate) that looks like this:

enter image description here

W column in this table means Fiscal Week.

I tried using this aproach:

    LastYearOnlineRevenue = 
    "LastYearOnlineRevenue",CALCULATE(SUM(RevenueByDate(Revenue)),FiscalCalendar(FiscalYear) = 
    YEAR(TODAY())-1 && RevenueByDate(Channel) = "Online")

If you can help me with at least one column, I am assuming the logic will be the same for the other 3.
Thank you in advance.

Here is the location for sample data and .pbix file:
