If you look in help for NETWORKDAYS you can see you need ATP and there you
can see instructions to install
it as well. 1 minute in help would have told you that

keep the office/excel cd handy, select ATP from toolsadd-ins and follow the
instructions

How do I install the networkdays function! Help tells me how to use it
but,
it doesn't exist in my system.

Formula as follows: =NETWORKDAYS(A2,A3,A4:A6)

Followed the instructions purrfectly, but alas the only answer I get is
#NAME?

Spent over an hour on the formula... I finally did it in 10 mins with my
daughters calculator.

Help for next time!!
