Let me guess (since you didn't say, and I forgot to ask).
You're using Access 2000 or newer.
The code you're trying to use is DAO, whereas, by default, Access 2000 and
newer use ADO.
With any code module open, select Tools | References from the menu bar,
scroll through the list of available references until you find the one for
Microsoft DAO 3.6 Object Library, and select it. If you're not going to be
using ADO, uncheck the reference to Microsoft ActiveX Data Objects 2.1
Library
If you have both references, you'll find that you'll need to "disambiguate"
certain declarations, because objects with the same names exist in the 2
models. For example, to ensure that you get a DAO recordset, you'll need to
use Dim RST as DAO.Recordset (to guarantee an ADO recordset, you'd use Dim
RST As ADODB.Recordset)
The list of objects with the same names in the 2 models is Connection,
Error, Errors, Field, Fields, Parameter, Parameters, Property, Properties
and Recordset
