           $results = mysqli_query($conn, $sql);

               if(mysqli_num_rows($results) < 1){
                   echo "No items";
                }else{
                  $new_sql    = 'SELECT
                                item_added,

    It looks like its because you're using an aggregate function SUM() without a GROUP BY. In the $new_sql query, try adding "GROUP BY item_added" right before "ORDER BY id".
