Index was outside the bounds of the array

i have a datatable called onlynewwithstatuschange

 DataTable onlynewwithstatuschange = new DataTable();
            onlynewwithstatuschange.Columns.Add("CUSTOMER", typeof(string));
            onlynewwithstatuschange.Columns.Add("NAME", typeof(string));
            onlynewwithstatuschange.Columns.Add("ADDRESS", typeof(string));
            onlynewwithstatuschange.Columns.Add("ADDRESS 2", typeof(string));
            onlynewwithstatuschange.Columns.Add("CITY", typeof(string));
            onlynewwithstatuschange.Columns.Add("STATE", typeof(string));
            onlynewwithstatuschange.Columns.Add("ZIP CODE", typeof(string));
            onlynewwithstatuschange.Columns.Add("PARENT", typeof(string));
            onlynewwithstatuschange.Columns.Add("TELEPHONE", typeof(string));
            onlynewwithstatuschange.Columns.Add("FAX", typeof(string));
            onlynewwithstatuschange.Columns.Add("TERMS OF PAYMENT", typeof(string));
            onlynewwithstatuschange.Columns.Add("COUNTRY", typeof(string));
            onlynewwithstatuschange.Columns.Add("CURRENCY", typeof(string));
            onlynewwithstatuschange.Columns.Add("STATUS", typeof(string));
            onlynewwithstatuschange.Columns.Add("STATUS CHANGED", typeof(string));
            onlynewwithstatuschange.Columns.Add("LONG", typeof(string));
            onlynewwithstatuschange.Columns.Add("LAT", typeof(string));

i am doing a status change check earlier in the code and adding those values to another datatable called tempchange.

then running the following code:

foreach (DataRow temp in tempchange.Rows)
            {
                DataRow[] foundRows = c.Select("CUSTOMER = '" + temp["CUSTOMER"].ToString().Trim() + "'");
                if (foundRows.Length != 0)
                {
                    onlynewwithstatuschange.Rows.Add(foundRows[0].ToString(), foundRows[1].ToString().Trim(), foundRows[2].ToString().Trim(), foundRows[3].ToString().Trim(), foundRows[4].ToString().Trim(), foundRows[5].ToString().Trim(), foundRows[6].ToString().Trim(), foundRows[7].ToString().Trim(), foundRows[8].ToString().Trim(), foundRows[9].ToString().Trim(), foundRows[10].ToString().Trim(), foundRows[11].ToString().Trim(), foundRows[12].ToString().Trim(), foundRows[13].ToString().Trim(),[b] temp[1].ToString()[/b] - getting from the temp change table so the use can see the status was changed from what, foundRows[14].ToString().Trim(), foundRows[15].ToString().Trim(), foundRows[16].ToString().Trim());
          }
            }

i counted the array and there are 17 values present and including the temp[1] it comes to a total of 18 values and the onlynewstatuschange datatable  has 18 columns so why then am i getting the index was outside the bounds of the array error?
