                UlFileName = "MyXlxs/" & System.IO.Path.GetFileName(myFile1.FileName)
                '*** Save Images ***'
                myFile1.PostedFile.SaveAs(Server.MapPath(UlFileName))
                'myFile2.PostedFile.SaveAs(Server.MapPath(UlFileName))
                Dim excel As New FileInfo(Server.MapPath(UlFileName))
                Using package = New ExcelPackage(excel)

                    Dim workbook = package.Workbook
                    '*** Sheet 1
                    Dim worksheet = workbook.Worksheets("sheet3")
