Two approaches:

1. Use the UDF, (or something like it) to set a Conditional Format.
2. Put the UDF or related UDF in a worksheet cell and use a Calculate Event
Macro to paint formats based upon the value returned.

Thanks, any advice to get it?
I used the UDF since I've to manage complex conditions.

A UDF cannot directly change the format of a cell.

Suppose I have a value in A1 and the formula
=FormatCell(A1), calling the following macro, in B1

Function FormatCell(a As Range)
a.Cells(1, 1).Select
Selection.Font.Bold = True
Selection.Font.ColorIndex = 3
End Function

Why I hav'nt A1 formatted?
I have breakpointed the macro and it triggers when I change the A1
value.
