I spoke too soon! When the value of C4 changes to something besides #N/A,
the text does not change back from white. So changing the cells to a
relative reference does not make conditional formatting work...

Hi

Your problem is that you are using an absolute cell reference, change
the formula to =ISERROR(A1)

Notice the $ signs has been removed to indicate that it is a relative
reference.

I'm applying the conditional format =ISERROR($A$1) to change the text of
cells displaying #N/A to white, as recommended by every conditional
formatting guide on the Internet. However, when applied to a range of cells,
they all turn white!!

Cell A1 has a formula that provides a #N/A error, in the same way that the
desired cells produce an #N/A error:

The cells that need to be white are coded =VLOOKUP(B4,SHEET1,10) where B4 is
='SHEET2'!C4. C4 is blank, so B4 returns 0. The result is #N/A. (When C4 is
no longer blank, B4 displays data and needs to be visible.)

This is the only conditional format used in the spreadsheet. I've tried to
find out if anyone else has this problem and had no luck.
