Hi! I am using Excel 2007 and would like to use conditional formatting (icon
sets-3 symbols) for a range of various negative through positive numbers. I
would like to see a result of a green symbol for any value between -10% to
10%, yellow symbol for any value between -11% to -50% and 11% to 50%, and a
red symbol for any value between -51% to -100% and 51% to 100%. How can I do
this?

This is a problem I encountered when I tried to add a new rule for the
negative numbers range through the conditional formatting rules manager, I
received this message: "One or more of the specified values is not a valid
percentage". Is this just not possible to do with the three symbol icon sets
and negative numbers?
