Answer 1

This solution works on almost all conditions. One restriction I found is when one of the subjects (Names) does no have data for any of the details (letters), but as of now the same occurs with all the other answers.

The formula assumes the data is located at B6:F30 (in order to ensure it can be applied regardless of the source range location).

The formula uses the Index\Match functions:

First, a MATCH to retrieve the position of the Name:

MATCH($H8,$B$6:$B$30,0)

With that info it uses INDEX to build a range that is used to obtain the position of the Detail (letter) using a second MATCH Function:

+ MATCH($I8,INDEX($B$6:$B$30, 1 + MATCH($H8,$B$6:$B$30,0))
:INDEX($B$6:$B$30,ROWS($B$6:$B$30)),0),

Adding the results of the first and second MATCH functions obtains the position of the Name`Detail` combination and uses it in an Index to the entire data. The position of the Data Column required is obtained with a Match:

INDEX($B$6:$F$30, 1st.MATCH + 2nd.MATCH,
MATCH(J$6,$B$6:$F$6,0))

With the results located at G6:L30 enter this formula in J8 then copy to J8:L30:

= INDEX( $B$6:$F$30,
MATCH( $H8, $B$6:$B$30, 0)
+MATCH( $I8, INDEX( $B$6:$B$30 , 1 + MATCH( $H8, $B$6:$B$30 ,0))
: INDEX( $B$6:$B$30, ROWS($B$6:$B$30) ),0),
MATCH( J$6, $B$6:$F$6, 0)),"")
