Why am I getting errors here ?

I don't know what is wrong with my code ?

FrogStats.cs
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double sum = 0;
            for(Frog i in frogs)
            {
                sum += i.TongueLength;
            }
            return sum;
        }
    }
}
Frog.cs
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;
        }
    }
}

You're close, but the instructions ask for the average length, not just the sum of all lengths.

So after you get the sum, you need to divide it by the number of frogs to get the average.
