  if (ddlperiodunit.Text.Trim() != "Till Further Order")

  {

      if (txtDt.Text.Trim() == "")

      {

          MessageBox("DEBARMENT START DT CAN NOT BE BLANK");

          txtDt.Focus();

          return;

      }

      if (TxtDebarmentPrd.Text.Trim() == "" || TxtDebarmentPrd.Text.Trim() == "0")

      {

          MessageBox("DEBARMENT PERIOD CAN NOT BE BLANK");

          TxtDebarmentPrd.Focus();

          return;

      }

  }
