the challange is not happy..

I can't see why this challange is giving me the: Bummer! Are you returning the average length of the tongues of the frogs in the array? ... message. Any ideas?

FrogStats.cs 
namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {
            double totalLength = 0.0;
            int i = 0 ;
            for ( ; i < frogs.Length ; i++)
            {
                totalLength+= frogs[i].TongueLength;
            }  
            return totalLength / ( i+1 );
        }
    }
}
Frog.cs 
namespace Treehouse.CodeChallenges
{
    public class Frog
    {
        public int TongueLength { get; }

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

In the return statmet use the frogs.Length again its the total number of values so you can divide with it :) And pls declare the index variable "i" inside the for loop it´s made for it ^^

namespace Treehouse.CodeChallenges
{
    class FrogStats
    {
        public static double GetAverageTongueLength(Frog[] frogs)
        {   
            double totalLength = 0;
            for (int i = 0; i < frogs.Length ;i++)
            {
                 totalLength += frogs[i].TongueLength;
            }  
            return totalLength /frogs.Length;
        }
    }
}
