I keep getting error cannot find table 0

DataSet ds = new DataSet();
           DataRow[] result = ds.Tables[0].Select("Team = '" + listBox1.SelectedItem + "'"); // filter result set
           DataTable dtPlayerInfo = new DataTable();
           dtPlayerInfo = result.CopyToDataTable();



           DataTable dtCloned = dtPlayerInfo.Clone();
           dtCloned.Columns[3].DataType = typeof(double);
           dtCloned.Columns[2].DataType = typeof(double);

           foreach (DataRow row in dtPlayerInfo.Rows)
           {
               dtCloned.ImportRow(row);

           }
           // Avg hit of team
           double hitsAvg = dtCloned.AsEnumerable()
               .Average(r =>
               r.Field<double>("hits"));

           // Avg bat of team
           double atBatAvg = dtCloned.AsEnumerable()
               .Average(r =>
               r.Field<double>("atBats"));

           // Actual Avg of team
           double teamAvg = hitsAvg / atBatAvg;
           DataTable dtPlayerAvg = new DataTable();
           DataRow rowPlayer = dtPlayerAvg.NewRow();
           dtPlayerAvg.Columns.Add("Player", typeof(string));
           dtPlayerAvg.Columns.Add("Batteing Avg", typeof(double));

           for (int i = 0; i < dtCloned.Rows.Count; i++) ;
           {
               double AvgPayer = Convert.ToDouble(dtCloned.Rows[3]) / Convert.ToDouble(dtCloned.Rows[2]);
               if (teamAvg <= AvgPayer) ; // checked palyer Avg to Team Avg
               {
                   dtPlayerAvg.Rows.Add(dtCloned.Rows[0].ToString(), Math.Round(AvgPayer, 4));

               }
           }

           DataView view = dtPlayerAvg.DefaultView;
           view.Sort = "Batteing Avg DESC ";
           //This cannot be done with the original data table. so created a new, sorted one:
           DataTable sortedDate = view.ToTable();
           dataGridView1.DataSource = sortedDate;
