If the ATP isn't installed you'll get a #NAME? error, not a #VALUE! error.

That's what Help says, Biff, but it ain't so. =NETWORKDAYS(A1,B1) gives a
#VALUE! error if ATP is switched off............

when he copied data into the reference section all the formula stop working

That's where the problem is. But, what does that mean?

Like Wigi, my guess is that he hasn't installed the Analysis ToolPak.
NETWORKDAYS is a function only available through the TookPak

Hi
I created a worksheet with some cells which work out network days etc
from
some date columns everything working fine.
I sent the spreadsheet to a colleague and when he opened it it looked
fine
to. However when he copied data into the reference section all the
formula
stop working and return #Value#. As far as I can tell the formulae are
correct. Retyping them has no effect.
The only difference I can see is he is running excel 2003 sp3 whilst I
created the workbook in exel 2003 sp2.
I get the same problem whenever I put new data into the spreadsheet if
the
machine is running sp3.
Is this a known issue and is there a workaround or am I goosed on this
one?

And how does the formulas that give the error look like?
