Try this for your Conditional Formatting formula in A1:

=COUNTIF(B1:Z1,"")0

Looking for a way to indicate if a range of cells contains a blank cell.
Tried to use conditional formating to change A1 to a red font if any cell in
the range b1-z1 is blank. Can't seem to get conditional formatting to work,
any ideas?

Thanks
