# 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;
}
}
}
}
```
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 itΒ΄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;
}
