Try something like

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

The NETWORKDAYS function requires that the Analysis Tool Pack add-in be
loaded. If it is not, you'll get a #NAME error.

Hello everyone.

I have a column of "begining" dates and another column
with "ending" dates. I'd like Excel to calculate the
weekdays between the two dates. For example, in the first
cell in column A I would have 10/01/03 and in the first
cell of column B I would have 10/16/03. I'd like Excel to
give me the number of weekdays within this time span,
which in this case would be 12. BUT, if the the "ending"
date is empty I'd like Excel to provide "today's" date.

I don't know if this can be done. Any help any of you
could provide would be very much appreciated.
