从水平表垂直获取多个匹配值？

Question

I came across this formula which works well with tables which have data listed vertically, however, I am having difficulty trying to apply this to a horizontal set of data.

I tried changing the ranges etc. without any success and hope someone can help out.

Here's the formula:

{=IF(ISERROR(INDEX($A$1:$B$8,SMALL(IF($A$1:$A$8=$I$5,ROW($A$1:$A$8)),
   ROW(1:1)),2)),"",INDEX($A$1:$B$8,SMALL(IF($A$1:$A$8=$I$5,ROW($A$1:$A$8)),
   ROW(1:1)),2))}

The website where I found this is here:

I would like to get this to work with the

Thanks for your help!

Cheers,

Stands to reason that changing A1:A8 to A1:H1 (rows of data into columns of data) means you also have to change the INDEX range and ROW($A$1:$A$8).

=IFERROR(INDEX($A$1:$H$2, 2, SMALL(IF($A$1:$H$1=$I$5, COLUMN($A:$H)), ROW(1:1))),"")

The newer IFERROR reduces the code and redundant calculation.
