Excel Conditional Formatting

[brewster56]

I have a formula in C19 that calulates a percentage. Everything works fine.
What I want to do is have the color of the cell change when a certain
threshold is met. Under CF I created the following set of rules :

=$C$19=0 format green
=$C$19>0 format blue
=$C$19<0 format red

Seems to work except the same rules get appended over and over again every
time C19's percentage changes. If C19 changes 9 times I end up with 6
additional rules (original 3 plus 6 additional - total 9). Not good as C19
can change dozens of times in a month. Any guidance ?

Can you clarify what is going wrong? The way you wrote your post, it sounds
like whenever the value of C19 changes, XL is creating additional CF rules.
(something I've never heard of before)

The way you have it initially setup, (and the way CF works) whenever the
value of C19 changes, it should evaluate it using the CF rules and color it
appropriately.

What are these 6 additional rules that are being created?
