compare dates

[Vic]

I have invoice numbers in column A (1234567ABC)
Date of invoice is in column B in this format 31-Mar-09
Date of product received is in column C in this format 04/15/09

I need to highlight in yellow each cell in column B (date of invoice) if it
is greater than a cell in column C (date of product received).

Hi Fred,

This did not solve anything.

My taks is to highlight B cells if they are greater than C cells. Please
keep in mind that some C cells may be blank (product was not received yet) -
I don't want to highlight corresponding B cell in this case.

Thank you.

Your problem likely is that column B is not a date, it's text. So you need
to force Excel to evaluate it. At the same time, add the check for column C
being blank. The following will do what you requested:

=AND(C1<>"",--B1>--C1)

Regards,
Fred.
