Thanks, Raj. That worked. My night is saved.

Hi Stormsailor

Try this formulae (assuming received date is in A1 cell and shipped date is
in B1 cell). in C1 where you need the difference try this formulae

=IF(B1="",TODAY()-A1,B1-A1)

This shall suffice your requirement.

Regards,
Raj

I have 2 columns, "received" and "shipped to customer", in standard date
format. I want to show a third column that shows the number of days in
between. I know I subtract one from the other. However, I also have blanks
in the shipped column for product that has not yet shipped out. For days
between the columns, I want it to treat blank cells as today's date. How do
I do this?
