If it isn't even installed (a distinct possibility) then no.

You would need to write your own function.

Hi

if I want to use the NETWORKDAYS function in a spreadsheet
that will be sent to colleagues and forwarded by them
elsewhere is there a bulletproof* way of getting round the
problem of the end user not having the Analysis Toolpak
installed? i.e. I want the function to work
without "people having to mess around with the add-in
manager" - many of them will never have used it (even if
they should have <g)

THANKS

Tim

* e.g. creating the function in VB in the workbook's
modules etc
