Try
Sdate: Format([TableName].[Date],"yyyymmdd")
If that works then you know the problem is that you have used Date as a
field name when "Date" is a reserved word and refers to the Date() function.
If that fails, try a test where you apply a format to some other field. IF
you still get the message, then check your library references and make you
are not missing a reference.
To do its job, Access makes use of various external program and object
libraries. If you move a database from one machine to another, these
references may be "broken".
When this happens, you need to take steps to let Access repair the
reference(s) ON THE COMPUTER WHERE THE FAILURE IS OCCURING.
Here are MVP Doug Steele's instructions for how to do it:
*** Quote ***
On the machine(s) where it's not working, open any code module (or open the
Debug Window, using Ctrl-G, provided you haven't selected the "keep debug
window on top" option). 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)
For far more than you could ever want to know about this problem, check out
http://www.accessmvp.com/djsteele/AccessReferenceErrors.html
Just so you know: the problem will occur even if the library that contains
the specific function that's failing doesn't have a problem.

When attempting to run a query that includes the 'Format' function in
Access
2007 I get the following error message:
Undefined function 'Format' in expression. (Error 3085)
The expresion is written as:
SDate: Format ([Date],"yyyymmdd")
It works fine in Access 2003 but fails in 2007.
What to do?
