 void GetTEam2()
        {
            OleDbConnection dbconn = new OleDbConnection(System.Configuration.ConfigurationManager.ConnectionStrings["AccessVisit"].ToString());
            dbconn.Open();
            //  string sql = "select ShortTeamName,Category,City,TeamID,Logo,TeamColor,TeamFont,ForumID,Tickets from theredzone.NFLTeam where Category like 'AFC%' and (ShortTeamName IN(select Team from theredzone.NFLHeadlines)) ORDER BY Category, City, TeamID ";
            string sql = "SELECT distinct [ShortTeamName] from NFLTeam where Category like 'NFC%'";
            OleDbDataAdapter adt = new OleDbDataAdapter(sql, System.Configuration.ConfigurationManager.ConnectionStrings["AccessVisit"].ToString());
            DataSet ds = new DataSet();
            adt.Fill(ds);
            rptNFC.DataSource = ds;

            {
                DataSet dsTEmp = new DataSet();
                Label lblAFCTEam = (Label)e.Item.FindControl("lblAFCTEam");
                dsTEmp = oDs1;
                dsTEmp.Tables["AFC"].DefaultView.RowFilter = "ShortTeamName = '" + lblAFCTEam.Text  + "'";
                Repeater ChildRep = e.Item.FindControl("rptAFCLink") as Repeater;
