Depending on your Cursor Type and Cursor Location (if you are using a recordset to update) this value may not be available directly with Access 97, so you may have to resort to doing something like:

Select Max(ID) + 1 As LastID From Table1

before you update or:

Select Max(ID) + 1 As LastID From Table1

after you update.

This has complications when this database can be hit by multiple users.

It is also dependant on the provider.  Are you using the Jet 4.0 provider?

Why not run a SQL statement like "Select MAX(autonumberfieldname) FROM TableName" right after you insert the new record?
