Help with DCount

The Date functions are in the VBA library, but that's usually irrelevant,
since the VBA library is the last library Access checks, and any broken
reference will mean that it won't find functions in the VBA library. (It's
done this way so that you can override built-in functions with functions of
your own)

My normal advice for trying to fix References problems is:

Open any code module, then select Tools | References from the menu bar.
Examine all of the selected references.

If any of the selected references have "MISSING:" in front of them, unselect
them, and back out of the dialog. If you really need the reference(s) you
just unselected (you can tell by doing a Compile All Modules), go back in
and reselect them.

If none have "MISSING:", select an additional reference at random, back out
of the dialog, then go back in and unselect the reference you just added. If
that doesn't solve the problem, try to unselect as many of the selected
references as you can (Access may not let you unselect them all), back out
of the dialog, then go back in and reselect the references you just
unselected. (NOTE: write down what the references are before you delete
them, because they'll be in a different order when you go back in)

In the meantime, see whether

VBA.Year(VBA.Now())

works. If it does, it may well be that there's something in the database
named either Year or Now. Since both of those are reserved words, they
should not be used for user-defined objects.

Hi

Thanks to you both for replying. I've managed to get it working using
the following:

=DCount("[Reference Number]","[Newsletter Database]"," [Newsletter
Database]![Year Born] between (Year(Now()) - 18 ) and (Year(Now()) - 25
) ")

Thanks again
