what' wrong with this bool method

there is no error, but It says "Did you create a parameter in your method named distanceToFly?".. how do I fix this?

Frog.cs
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

        public Frog(int tongueLength)
        {
            TongueLength = tongueLength;

            public bool EatFly(distanceToFly);
            {bool canEat = distanceToFly <= tongueLength;
             return canEat;
            }
        }
    }
}

A few things wrong ...

  1. need a type int before the method parameter distanceToFly
  2. EatFly needs to be outside of the scope of the Frog constructor
  3. typo: use TongueLength, not tongueLength for your comparison
  4. typo: unneeded semicolon at end of function's first line
namespace Treehouse.CodeChallenges
{
    class Frog
    {
        public readonly int TongueLength;

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

        public bool EatFly(int distanceToFly)
        {
            bool canEat = distanceToFly <= TongueLength;
            return canEat;
        }
    }
}

wow, thank you so much. It works well.

I didn't even realize the EatFly was inside the sope of Frog.... damn...
