Error: An object reference is required to access non-static member `Treehouse.CodeChallenges.LexicalAnalysis.WordCount'

Hi there, I'm getting this error and have no idea why, please help!

LexicalAnalysis.cs
using System.Collections.Generic;

namespace Treehouse.CodeChallenges
{
    public class LexicalAnalysis
    {
        public Dictionary<string, int> WordCount = new Dictionary<string, int>();

        public void AddWord(string word)
        {
            int num;
            if (WordCount.TryGetValue(word, out num))
            {
                WordCount[word]++;
            }
            else
            {
                WordCount.Add(word, 1);
            }
        }

        public static Dictionary<string, int> WordsWithCountGreaterThan(int num)
        {
            Dictionary<string, int> newDic = new Dictionary<string, int>();
            foreach (KeyValuePair<string, int> pair in WordCount)
            {
                if (pair.Value>num)
                {
                    newDic.Add(pair.Key, pair.Value);
                }
            }
            return newDic;
        }
    }
}

The problem is that your WordsWithCountGreaterThan method is declared as static which it should not be. Things tend to get complicated when you mix static and non static stuff together.

Simply removing static from the method declaration will allow you to pass the challenge, since the rest of your code seems correct.

Thank you!
