I'm able to use SUMIF to return sum of all cells that fit one criteria:
=SUMIF(DATA!$U$3:$3, "Previous Age",DATA!$U9:9)
However, I'd like to add another criteria: to match $F$2 with 1st criteria's OFFSET (,,-3).
=SUMIF(DATA!$U$4:$4, DATA!$U$3:$3&OFFSET(DATA!$U$3:$3,,-3),"Previous Age"&$F$2)
=SUMIF(DATA!$U$4:$4, (DATA!$U$3:$3="Previous Age")*(OFFSET(DATA!$U$3:$3,,-3)=$F$2))
The above two formulas do not work, but hoping it still conveys what I'm trying to do.
the cells in question are highlighted in teal.
In this case SUMIF can't be used as its 2nd parameter must be a valid range otherwise you will get:
ERROR Argument must be a range.
Try:
=SUM(LET(x, WRAPROWS(FILTER(DATA!U4:4,
REGEXMATCH(DATA!U3:3, "Previous Age|Rope Type")), 2, ),
IFNA(FILTER(INDEX(x,,1), INDEX(x,,2)=F$2))))
Basically it's extraction of columns wrapped into table and filtered down before summing it:
=SUM(LET(x, WRAPROWS(FILTER(DATA!AA4:4,
REGEXMATCH(DATA!AA3:3, "Previous Age|Rope Type")), 2, ),
IFNA(FILTER(INDEX(x,,2), INDEX(x,,1)=F$2))))
