Odbc link Sybase DB. Fields pat_ID is number, Long int, Primary, index, no
duplicate. Some how I couldn't add new record. Error "Type mismatch" and the
field pat_ID=null (?) Thanks you in advance !
 
You can't use DMax on a recordset.

Try:

!pat_id = Nz(DMax("pat_id", "dbo_A", "lname = '" & _
Trim(Me![lname]) & "' and fname='" & Trim(Me![fname]) & "'"), 0) + 1

Using single quotes on names, though, will lead to trouble when the name has
an apostrophe in it (D'Arcy, O'Reilly, etc.) You'd be better off using

!pat_id = Nz(DMax("pat_id", "dbo_A", _
"lname = '" & Replace(Trim(Me![lname]), "'", "''") & _
"' and fname='" & Replace(Trim(Me![fname]), "'", "''") & "'"), 0) + 1
 
Wow - You are wonderful ...
Best Regards!
