Hi Mark

Maybe because of the way that binary representations of numbers are
held, your Zero values are not truly zero but
0.0000000000565 or some such value.
As such, they will shade green according to the test.
If you made the test for green greater than 1, then any value from say
0.0000000001 through 0.9999999999
will remain uncoloured.

Greetings all:

I am running XP Pro/Excel 2003.

I have a spreadsheet that I created to track my copy count for a
copier on a
maintenance agreement so that I know how I am doing and to avoid those
expensive over contracted amount pay per page costs (cool, I know).

In any event, I have a colum that has a conditional format which will
shade
the cell red if I am over my current allotment, and shade the cell
green if I
am under. Simple enough, however I don't want any shading if the cell
is
blank.

I have some fixed data in these cells:

B3 is my contracted copy amount
B7 is my starting copy count
A7 is my starting agreement date

I Have the following columns

A Current Date
B Current Machine Count
C Count to date formula =IF(ISBLANK(B8),"",(B8-$B$7))
D Day of Contract formula=IF(ISBLANK(B8),"",(A8-$A$7))
E Scheduled Count formula =IF(ISBLANK(B8),"",(($B$3/365)*D8))
F Over/Under Column formula=IF(ISBLANK(B8),"",(E8-C8))

It is this column F where I have the conditional format to shade it
red or
green depending on if my current count is over or under my scheduled
count.
The way it currently is working is that no number will print, but it
will
shade the cell green. I assume it might have something to do with the
fact
that I am using ISBLANK in the formula, but I really don't want to
have to
copy and drag the conditonal format down each time I update the next
line of
the worksheet with new data.

The conditonal format I am using is:

If f8 is less than 0 it will shade the cell red
If f8 is greater than 0 it will shade the cell green

I have tried using a third condition of:

If f8 is 0 then no shading, but this will not work. I always get a
green
fill.

Anyone have any ideas?

Sorry for the lenght, but I feel more info is better than less!
