size=2>Early version of Access had a sample of code for a function called
CNulls(), I think, in the help files. You had to build your own Null
replacement function because Nz didn't exist until Access started using
VBA. I stopped using it when Nz became available and have never had any
problems.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2>...this is a prime example of
Microsoft geek writing ...the reason I never buy anything from MS Press
...I'll be damned if I can figure out what it is that the nz function
doesn't quite perform "as expected"? :(</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>...I use nz in several AXP apps and to date
have noticed nothing that I didn't expect ...but with this kind of crap KB,
I'll be certain to waste a lot of time the next time I use it, just futzing
about looking for some kind of error in the returned data
:(((((</FONT></DIV>

face="Comic Sans MS" size=2> that says the Nz function works in 2002 but
it may not work as expected! Say what?? It works, but it
doesn't?</FONT></P>
<P><FONT face="Comic Sans MS" size=2>Has anyone run into this? Nz
isn't always the most appropriate function, but I've never seen it fail,
at least not that I knew about. We use this a lot, and I'm concerned
about migrating our apps from 97 to 2002 and having a lot of code fall
over. I wondered if it could be the result of not passing in the
optional argument, but the article seemed rather vague to me. Does
anyone else have first-hand knowledge of the problem?</FONT></P>
