Hi,
You might want to try the following formula:
=IF(ISNA(LOOKUP(B16,$N$16:$S$34)),"",LOOKUP(B16,$N$16:$S$34))
The above will convert all #N/A to blank cells.
Alternatively, if you want to convert all error lookup value to blank cells, then can try the following:
=IF(ISERROR(LOOKUP(B16,$N$16:$S$34)),"",LOOKUP(B16,$N$16:$S$34))
