If you need the #N/As, use Conditional Formatting:

Format/Conditional Formatting...
CF1: Formula Is =ISNA(A1)
Format: (Font color = background color)

If you don't need the #N/A's, then you're probably better off
eliminating them from your sheet:

=IF(ISNA(MATCH(A1,J:J,FALSE)),"",VLOOKUP(A1,J:K,2, FALSE))

I am using a worksheet that will has very many error messages (#N/A). These
messages are the result of a Vlookup that's supposed to get its input from a
dropdown, only the dropdown may or may not get selected. I need to make it
where the error messages are just whited out and you can't see them.
