Help with cascading totals

I was hoping to get some support on how to create a cascading total. I have followed this amazing article exactly; however, I am stumped when getting the final output.

I have essentially gotten my formulas to work and get my signs correct. However, now that I am ready to get the subtotals into the report and the drill down functionality I am stumped and needing some assistance.

I am stuck here basically and need to figure out how to get my current measures in a drill down table with the is header details as the second level of detail. All of the columns beside my first one are the top level of the hierarchy and do not need to be columns but actually need to be in some sort of switch function or something that will give me the drill down functionality I need. So the Test Sum is correct; however, I also need to incorporate a Sum that is for Total Revenue, Total Production Costs, Total Depreciation, Total Indirect and so forth and so on and believe the switch function may give me that but I can't figure it out.
