Additional help needed with existing formula using LAMDA- Excel 365

I reorganized the sample file, so each table now contains the same number of columns, in the same order, as the updated SheetMap. The only thing I had to change about the formula (from rev3.0) was the _cId variable to set the field mapping:

=LET(
   _rep, RESULTS!$A$2,
   _beg, RESULTS!$B$2,
   _end, RESULTS!$C$2,
   _lst, RESULTS!$A$5:$A$12,
   _inc, (RESULTS!$E$5:$E$12="EXCEED")+(RESULTS!$E$5:$E$12="NOT MET"),
   IF(
      NOT(OR(_inc)),
      "[no records found]",
      LET(
         VALλ, LAMBDA(lbl,tId,csv,LAMBDA(x,CHOOSE(x,lbl,tId,csv))),
         EXPλ, LAMBDA(array,[rws],EXPAND(array,rws,9,"")),
         INCλ, LAMBDA(field3,field2,(field3=_rep)*(field2>=_beg)*(field2<=_end)),
         _fId, SEQUENCE(,9),
         _cId, VSTACK("1,2,3,4,,,5,13,14", "1,2,3,4,,6,5,10,11", "1,2,3,4,,,5,11,12", "1,2,3,4,6,,,8,9",
               "1,2,3,4,,,5,11,12", "1,2,3,4,7,6,5,12,13", "1,2,3,4,6,,5,14,15", "1,2,3,4,6,7,8,14,19"),
         REDUCE(
            EXPλ("Field"&_fId,2),
            FILTER(MAP(_lst,SEQUENCE(ROWS(_lst)),_cId,VALλ),_inc),
            LAMBDA(acc,val,
               LET(
                  tbl, INDIRECT("tbl"&SUBSTITUTE(SUBSTITUTE(val(1)," ",),"-",)&"[#ALL]"),
                  arr, SORTBY(EXPλ(CHOOSECOLS(tbl,--TEXTSPLIT(val(3),",",,1))),SORTBY(_fId,TEXTSPLIT(val(3),",")="")),
                  bdy, DROP(arr,1),
                  qry, FILTER(bdy,INCλ(CHOOSECOLS(bdy,3),CHOOSECOLS(bdy,2))),
                  VSTACK(acc,EXPλ("["&val(2)&"] "&val(1)&":"),EXPλ(TAKE(arr,1)),EXPλ(IF(ISBLANK(qry),"",qry),ROWS(qry)+1))
               )
            )
         )
      )
   )
)

I also added a 'FieldMap' worksheet to the attached revision, so you can see how the field mapping was generated (there are 4 formulas highlighted in blue, as well as a note showing the formula used as the Data Validation List Source for range C5:U12).

If you're still having issues applying these methods to your master workbook, I'm afraid there's not much more I can do to help aside from gaining access to your actual workbook to troubleshoot the problem.

Best of luck!
