Hi David

Many thanks for this, but can you tell me what format the respective
columns
need to be in so that this formaula will work?

Cheers.

Hi

I have a spreadsheet with 5 columns:

A = date an e-mail received
B = time e-mail received on that date
C = date e-mail replied to
D = time e-mail replaied to on that date e-mail
E = was the e-mail replied to within agreed time limit?

The agreed time limit is 24 hours.

I'd be happy enough coming up with a formula to input Y or N into
colmun
E,
if I only knew how to subract a time AND date from another time and
date.

Can anyone advise, please?

Many thanks.

Keith
