Index match (or) function

would like to index column H match column N with Column CK or CL

=ifna(index(columnH,match(coumnN,columnCK or ColumnCL),0)),"")

How can I write where it looks at Column CK if no match it will look at Column CL, if there’s a match it will show ColumnH value?

if tried using * between column function, also tried using &

i need to incorporate $CL$11:$CL$42 into this function

=IFNA(INDEX($H$11:$H$42,MATCH(N36,$CK$11:$CK$42,0)),"")

example:

Row 10
column H = 100

column N = @CA

column CK = CA

column CL = @CA

side note:

I do not need both columns to Match, I only need one column to match (either or N36 will match CK column or CL column ) and come back with a value from Column H

thank you in advance for any help provided.

I think this should work but I have not tested as I don’t have sample data.

=IFNA(INDEX($H$11:$H$42,IFNA(MATCH(N36,$CK$11:$CK$42,0),MATCH(N36,$CL$11:$CL$42,0))),"")

Edited to add missing close parenthesis.
