Index match #n/a error

=INDEX(‘WRP WK1’.$O$14:$O$312,MATCH(A16&C16,‘WRP WK1’.$B$14:$B$313&‘WRP WK1’.$A$14:$A$313,0))

how do I fix this function to not show #n/a and to leave a blank with there is no value

thank you in advance for any help provided

Use the IFNA function.

Example:-

=IFNA(INDEX('WRP WK1'.$O$14:$O$312,MATCH(A16&C16,'WRP WK1'.$B$14:$B$313&'WRP WK1'.$A$14:$A$313,0)),"")

PERFECT ! THANK YOU MARK
