Create a public Action field named DisplayResult that takes an int parameter and a Func<int, int> parameter. Initialize

Please help I have no idea what I'm doing wrong here, Thanks.

Program.cs 
using System;

namespace Treehouse.CodeChallenges
{
    public class Program
    {
        public Func<int, int> Square = delegate (int number)
   public Action<int, Func<int, int>> DisplayResult  = delegate (int result, Func<int, int> operation){};  

        {return  number * number;};
    }
}

It looks like the (otherwise good) definition of DisplayResult got put in between parts of the definition of Square instead of after it.
