Dynamic Subtotal of column after each row entry has been multiplied by two-way lookup

[PrettyGood_Not Great]

Hi, I have a challenge to produce a column total above the header row, where the total is the sum product of the entire row, after each entry has been multiplied against the rate table. Currently showing in row A of the data table is the double XLOOKUP to find the rate.

Thanks to @Fluff for the solution in column H where this operation is being performed for the rows. The challenge here is to have the same results for the column totals, BUT it needs to produce a subtotal when filtering on the Charge Codes (column I). Anyone know a 365 solution to this?

Where are the blanks (or perhaps text)?...Are they in the main table?...columns K:Y in the example I posted?

And to which header row are you referring? Is it the main table...K2:Y2 in the example I posted? Are those sometimes blank?

Does the Skill/Rate column ever have blanks?

Yes to all. In the working file the J:Y range is templated for a large set of data, and associated structure, which will almost always have empty cells. For example, K2:Y2 is formatted for 5 years worth of months, but usually won't be populated for the full duration. J:J also will almost never be fully populated. and the data range K3:Y8 will be populated randomly.

I added error traps in both formulas to handle cases where blanks might appear, or text in the main table (see orange cells).

Nice! I only had to use the first IFERROR() for it to run correctly. You are too good, thank you!

You're welcome...glad to hear it's working okay.
