# i don't know what it is i am doing wrong.

can someone give me a few pointers on what i am doing wrong here please?

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

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

You've got a couple of things going on here. You are on the right track with your For loop, however you are trying to use the Name of the Class that is Frog instead of using the actual array of Frog objects. In your FrogStats.cs file, you need to add a variable that will add up all of your TongueLengths. Something like:

```int total = 0;
```

Your FOR loop starts off correctly:

```for (int i = 0; i < frogs.Length; i++)
{
```

However, because you are iterating through each item in the `frogs` array, you need to use that to pull values and essentially add them into the total.

```// Add each TongueLength to the total
total += frogs[i].TongueLength;
}
```

This will add up each TongueLength into the local variable `total`. Once you have done that you close out your for loop and you need to return the average. The formula for that is `<total>/<number of items>` so something like:

```return total/frogs.Length;
```

In the end it will look something like:

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