Code:
Private Sub cus()

Dim cnview As New ADODB.connection
Dim rsemployee As New ADODB.Recordset

Call connection(cnview, App.Path & "\Commissions.mdb", "endromida")
Call Recordset(rsemployee, cnview, "SELECT * FROM customer WHERE idcn ='" & txt1stID.Text & "'")

If rsemployee.RecordCount = 0 Then
MsgBox "The record you requested could not be found.", vbExclamation, "Medrar"
Exit Sub
End If


With rsemployee
txtFan.Text = .Fields!fname
txtFisNa.Text = .Fields!fsna
txtSecNa.Text = .Fields!sena
txtLasNa.Text = .Fields!trna  --- Null Error
txtFulNa.Text = .Fields!funame
txtMob.Text = .Fields!mobie
txtExpDate.Text = .Fields!exd
End With

Set cnview = Nothing
Set rsemployee = Nothing
End Sub
Run time Error
Null

how to accept null values?
