Hi

the only way i can get a cell to behave as you've described is either to
"delete" the contents of the cell using a spacebar - which doesn't delete it
but puts a space in it or have a formula such as =IF(A1A2,A1,"") in it,
which places a zero length text string in the cell - ie it isn't "blank"
either.

If the cell shading is the result of a formula then in the conditional
formatting choose
formula is and
type in
=AND(ISNUMBER(B1),B1=100)
where B1 is the cell you want to apply the formatting to.
and apply your formatting

Hope this helps
Cheers

I have a cell in which I want it formatted to a yellow background if the
value is = 100. I have formatted it and it works fine. However, when the
cell is blank, it is the yellow background color of the greater that 100
formatting. I just want the cell to be blank when it has no value. How can
I
do this? I have tried adding another "blank" formatting for when the cell
is
less than 100, but it doesn't work. Any ideas, or can this not be done?
