        rs.Fields("Contact_person") = TxtCperson.Text
        rs.Fields("contact_no") = TxtContactNo.Text
        rs.Fields("office_address") = TxtOfficeAdd.Text
        rs.Fields("email") = Txtemail.Text
        rs.Fields("website") = TxtWebsite.Text
        rs.Fields("fax_no") = TxtFax.Text
        rs.Update
        rs.Close
        MsgBox ("Data Saved")
        Call frmSupplier.Addtolistview
      End If
      End If
'      Call CloseConnection(con)
      Exit Sub

Okay, the part you tried to highlight in red is constantly returning zero and it should be something like...

... = Combo1.ListIndex

That is, if what you need is the index number but if your field is 1 based and not zero based like the combo then you will need to do

... = (Combo1.ListIndex + 1)

However, if you are wanting to retrieve the text listed/selected in the combo box then you need...

... = Combo1.Text

Good Luck

Okay, what that error is telling you is that you have a unique field ID or otherwise and you are trying to add a duplicate entry. So the question arises. Are you trying to add a duplicate entry or update an ID field? Perhaps a look at your table structure might help because if you have a field that is supposed to be a foreign key but you have it constricted with a unique constraint then that may be your problem.

Good Luck
