The following is an example where the button name is "btnSave" located on some form used to make entry(s) for the table(s) with a Click [Event Procedure]:
Private Sub btnSave_Click()
On Error GoTo btnSave_Click_Err
If Me.Dirty = False Then
Beep
MsgBox "No new information to save.", , ""
Else
DoCmd.RunCommand acCmdSaveRecord
DoCmd.GoToRecord , "", acNewRec
End If
btnSave_Click_Exit:
Exit Sub
btnSave_Click_Err:
Beep
MsgBox Err.Description, vbOKOnly, ""
Resume btnSave_Click_Exit
End Sub
Just in case you do not know how to add the code for the save button. To add the code open the form in Design View, click the button you are using to save records, open Property Sheet, go to Event tab, for On Click type or select [Event Procedure]. Then press and hold "Alt F11" or click the three little dots to the right of [Event Procedure], which will take you to where the button name_Click() is located. Simply copy and paste the aforementioned code (minus the following) between the Private Sub ...... and End Sub. Now save the newly added code in the VBA Editor and open your form in Form View to test it out.
