                    where t.IsChecked && t.IsConfirmed == true
                    select new
                    {
                        TransactionID = t.TransactionID,
                        RecordingDate = t.CreationDate,
                        TransactionDate = t.TransactionDate,
                        CreditAccount = t.CreditAccount,

                        Amount = t.Amount,
                        For = t.Description,
                        Project = getProject(t.ProjectID),
                        Head = getHead(t.HeadID),
                        CompanyID = t.CompanyID
                    }).ToList();

     advance = (advance.Where(a => a.CompanyID.Equals(Session[SessionController.Session_CompanyId]))).ToList();

     if (!string.IsNullOrEmpty(drpEmployee.SelectedValue) && drpEmployee.SelectedValue != "0" && drpEmployee.SelectedValue != "--Select--")
     {
         advance = (from a in advance
                    where a.CreditAccount == Convert.ToInt64(drpEmployee.SelectedValue)
