Hi Nick!
I'm a new ATVO user and I'm learning how to use scripts.
I used your code to test this feature:

using System;
using System.Data;
using ATVO.ThemesSDK;
using ATVO.ThemesSDK.Data.Entity;
using ATVO.ThemeEditor.ThemeModels;
using ATVO.ThemeEditor.Scripting.DotNET;
using System.Collections.Generic;

namespace Scripts
{
 public class LiveChampionshipPoints : IScript
 {
 private Dictionary<int, int> _pointSystem = new Dictionary<int, int>();
        private Dictionary<int, DriverContender> _standings = new Dictionary<int, DriverContender>();

 public object Execute(ThemeContentItem item, object value, string parameter, ISimulation sim)
 {
            // Make sure point system and standings are loaded
            LoadPointSystem(item.Theme);
            LoadStandings(item.Theme);

            // Update the points
            UpdateSessionStandings(sim);

            // Sort by points and assign position
            // This updates positions for drivers in the session AND drivers not in the session
            UpdateChampPositions();

            // Also update the champ results for drivers in the session
            // in case you are showing these somewhere else (in another widget)
            UpdateSessionChampResults();

            // Finally update our Custom Data Sets so the widgets are showing the new results
            UpdateDataSets(item.Theme);
            
 return value.ToString();
 }

        private void UpdateSessionStandings(ISimulation sim)
        {
            // Loop through entity results in the session and update the standings
            foreach (var result in sim.Session.Current.Results)
            {
                DriverContender driver;

                // Check if there is a driver in the session who was NOT in the standings csv
                if (!_standings.ContainsKey(result.Entity.Id))
                {
                    // This driver isn't in the standings yet, let's add him

                driver.Entity = result.Entity;

                // Add the champ points obtained during this race
                driver.LiveChampPoints = driver.ChampPoints + _pointSystem[result.Position]; // Or result.LivePosition to update during a lap
            }
        }

        private void UpdateChampPositions()
        {
            // Sort the standings by live champ points and assign positions in order

                {
                    // update the ChampionshipResult object
                    var champ = driver.Entity.ChampionshipResult;

                    champ.Position = driver.ChampPosition; // previous pos
                    champ.LivePosition = driver.LiveChampPosition; // updated pos
                    champ.Points = driver.ChampPoints; // previous points
                    champ.LivePoints = driver.LiveChampPoints; // updated points
                }
            }
        }

        private void UpdateDataSets(Theme theme)

 private void LoadPointSystem(Theme theme)

            if (_pointSystem.Count == 0)
            {
                // Read point system from an embedded spreadsheet
                // Two columns: position, points
                var sheet = theme.Spreadsheets.Find("points_system.csv");

                foreach (var row in sheet.Table.Data.Rows.OfType<DataRow>())
                {
                    var position = row[0];
                    var points = row[1];
                    _pointSystem.Add(position, points);
                }
            }
        }

        private void LoadStandings(Theme theme)
        {
            if (_standings.Count == 0)
            {
                // Read current standings from embedded csv
                // Columns: customer_id, position, carnumber, lastname, firstname, points
                var sheet = theme.Spreadsheets.Find("/csv/standings.csv");

 }

 public class DriverContender
 {
 public IEntity Entity {get;set;}
        public int CustomerId {get;set;}
        public string CarNumber {get;set;}
        public string Name {get;set;}
        public int ChampPosition {get;set;}
        public int ChampPoints {get;set;}
        public int LiveChampPosition {get;set;}
 public int LiveChampPoints {get;set;}
 }
}

So, here are the errors in ATVO Theme Editor:

LiveChampionshipPoints.cs (Line 74) 'Dictionary<int, DriverContender>.ValueCollection' does not contain a definition for 'OrderByDescending' and no extension method 'OrderByDescending' accepting a first argument of type 'Dictionary<int, DriverContender>.ValueCollection' could be found (are you missing a using directive or an assembly reference?)

And here are the errors when I'm using Visual Studio Code:

Sorry for this long post here.
If you can help me with this problem, I'll appreciate.

Thanks!
