EXCEL Lookup the same value that has multiple values

been stumped on this one and trying to find a solution:

I have 2 rows of data.

1: 14 14 12 11 10 5
2: 123 122 119 118 115 111

need to lookup 14 and return 123 in one cell and 122 in the next cell. all i can do now is 123 123.

any help or direction would be appreciated. i am able to do this if the data is vertical, but can't convert it to horizontal for some reason.

here is the code i used when the data was vertical:
=INDEX($b$1:$b$15,SMALL(IF($a$1:$a$15=I21,ROW($a$1:$a$15)-MIN(ROW($a$1:$a$15))+1,""),COLUMN($B$1)))) ctrl+shift+enter

thanks in advance!
