Two sections of my table cannot process data because MATCH formula is displaying "Value not available" (values are present in range), for other five sections MATCH formula works.
I've tried changing ranges, cleaning/trimming range (to remove hidden chars), for some weird reason second section works when I changed lookup range from $A$2:$A$1200 to $A$2:$A$1300 but left INDEX range at $A$2:$A$1200.
=CELL("address",INDEX($A$2:$A$1200,MATCH($AP8,$A$2:$A$1200)))
Expected result would be cell reference of first matching value in ascending order from lookup range, but first two sections are displaying #N/A error.
EDIT #1:
Data example:
A B C D
1 Name1 Name1
2 Name1 Name2
3 Name1
4 Name2
5 Name2
6 Name1
7 Name2
...(list is never completed as new data is always entered)
I want cell reference of specific Name that has been entered latest. In this case it would be
=CELL("address",INDEX(A1:A7,MATCH(B1,A1:A7)))
and expected result would be $A$6.

MATCH($AP8,$A$2:$A$1200)is doing a Nearest Match (see doc's here). You probably wantMATCH($AP8,$A$2:$A$1200,0)- chris neilsen
