Show value if it is a certain week in a month - expression

I need to build a spreadsheet that checks month (show values if dates are in the current month), I need to show something that looks like this:

I need the value DSO *(Which i calculate using this exspression - SUM(Customers_Aging_Exclude_Int[Customer Balance])/SUM(Monthly_Activity_DSO[Final Trx Amount]) 31 ) to show up to the side of each of those weeks above.

I want this to change according to the month.

So… next month would show March…then April…and so on…

I have built and rebuilt the structure - but i cannot seem to get it correct. This is what i currently have:

Does anyone have a suggestion for me here?
