# Not sure what I am doing wrong here?

Add a new method named ReverseNumbers that has a return type of IEnumerable<int> and uses a LINQ query to return the _numbers variable in reverse order.

NumberAnalysis.cs
```using System.Collections.Generic;
using System.Linq;

namespace Treehouse.CodeChallenges
{
public class NumberAnalysis
{
private List<int> _numbers;
public NumberAnalysis()
{
_numbers = new List<int> { 2, 4, 6, 8, 10 };
}

public IEnumerable<int> ReverseNumbers()
{
return _numbers.OrderbyDescending(n => n);
}

public IEnumerable<int> NumbersGreaterThanFive()
{
return _numbers.Where(n => n > 5 );  //from n in _numbers where n > 5 select n;
}
}
}
```

Your Code should definitely work. Below is my solution which worked fine. iÂ´ve experienced similar issues and the fix i found was simply to submit my code using a different browser. The browser that finally worked for me was Chrome.

```using System.Collections.Generic;
using System.Linq;

namespace Treehouse.CodeChallenges
{
public class NumberAnalysis
{
private List<int> _numbers;
public NumberAnalysis()
{
_numbers = new List<int> { 2, 4, 6, 8, 10 };
}

public IEnumerable<int> NumbersGreaterThanFive()
{
return _numbers.Where(n => n>5);
}

public IEnumerable<int> ReverseNumbers()
{
return _numbers.OrderByDescending(n => n);
}
}
}
```
