Dynamic named ranges are not woking with SUMIFS function

Hello Excel Forum:
My problem is that when I used dynamic named ranges with SUMIFS, I get a #Value! error.
The SUMIFS works when I use traditional cell references (B15: B26) style. The dynamic named ranges also work for SUM and AVERAGE on the same sheet. So I feel that the dynamic name ranges are correct. When I substitute the named ranges (Dy_Hrs) or (Dy_Fuel) in the SUMIFS function in place of the cell references, I get the error. Once I am convinced that the Dynamic ranges and the SUMIFS work, I want to move to VBA Code. See attached Workbook.

I am using SUMIFS to add the hours in Range (B15:B26), dynamic range but EXCLUDING the work categories of Contractor, Support, Stripping.

Any help would be appreciated
