adding sumation of certain columns within pivot table

Attached is a sample worksheet with a calculated item showing the difference between TOA and critical funding levels for different years.  I now want an aggregate of the TOA, Critical and difference for FY15 - 19 within the pivot table.  I added columns R, S & T as an example, but it's not within the pivot table.  Also attached is a PDF of a scanned page which was built strictly from "cut and paste".  This is not my preferred way to build the data.  I ultimately need to print a separate page for each MDEP.  Also, if I add the SAG to the pivot I get the error "too many records".  I haven't figured a way around this one yet either.  I'm working in Excel 2007.
