ODBC Error 3146 on rs.update

Hi,
Using MS Access, I have a form that is based on a table called Motion_Imagery. In the VBA of this code I want to take two fields on the form and add the data in those two fields to the last record that was added to table Online_Books. When I run my code I get the error when it gets to rs.update, here is my code:

Set db = CurrentDb()
Set rs = db.OpenRecordset("dbo_Filestream_Files", dbOpenDynaset, dbSeeChanges)

rs.MoveLast

rs.Edit
rs![Prefix_CTRL_NBR] = Me.Prefix_CTRL_NBR
rs![CTRL_ID] = Me.CTRL_NBR
rs.Update


Can you tell me what the problem is? Is this possible to do?
Thanks,
Sharon

 

Here is my code followed by my C# code. The error I'm getting is ODBC 3146 on the rs.Update

MS ACCESS:

Code:

Public Sub Load_Files_Click()
   Dim strSQL As String
   Dim intCntr As Integer
   Dim db As Database
   Dim rs As Recordset
   Dim FileStream
   
   On Error GoTo Err_Prefix_Ctrl_Nbr
   
   FileStream = Shell("C:\Development\GEOINT\GEOINT\bin\Release\GEOINT.EXE",
1)
   
   Set db = CurrentDb()
   Set rs = db.OpenRecordset("dbo_Filestream_Files", dbOpenDynaset,
dbSeeChanges)
     
   rs.MoveLast
       
   rs.Edit
   rs![Prefix_CTRL_NBR] = Me.Prefix_CTRL_NBR
   rs![CTRL_ID] = Me.CTRL_NBR
   rs.Update
   
Exit_Prefix_CTRL_NBR:
   rs.Close
   Set rs = Nothing
   Exit Sub
   
Err_Prefix_Ctrl_Nbr:
       If Err = 3146 Then
           MsgBox "Error Number: " & Err & " - " & Err.Description
           Resume Exit_Prefix_CTRL_NBR
       End If
       
End Sub
