Try this:
=IF(SUMPRODUCT(--(A1:A10<B1:B10)),"Warning","")

Is that something you can work with?

I am trying to compare each cell to the one below and this for a whole
range.
The difficulty comes form the fact that I need to have an alert in one
formula.
Something like
if (A1:A10<B1:B10, "Warning", "")
the warning will appear only if A1<B1 or A2<B2 or A3<B3 and so on.
Any idea?
THanks
