Error CS1061 as a result of Error CS0103

Question

What am I missing here my code looks exactly the same as the videos? 
TreehouseDefense.Point does not contain a definition for X and no extension method X of type TreehouseDefense.Point could be found 
the name X does not exist in the current context
the name y does not exist in the current context
namespace TreehouseDefense
{
  class Point
  {
    public readonly int x;
    public readonly int y;
public Point(int x, int y) 
        {
            X = x;  // put the value from the argument into the readonly variable.
            Y = y;
        }
  }
}

```csharp
namespace TreehouseDefense 
{ 
    class Point 
    { 
        public readonly int X; 
        public readonly int Y;
    public Point(int x, int y) 
    { 
    X = x; // put the value from the argument into the readonly variable. 
    Y = y; 
    }
}
}
```
Be aware that C# is case sensitive. 
So in your case, the problem is that the integers that you're initializing are lower case letters, x and y.
In your method you're using the parameters: lower case x and y.
So when you're in the scope and trying to set the uppercase letters equal to the lower case letters, it simply doesn't know what the upper case letters are, as you didn't define them anywhere.
So to solve your problem, simply make the x and y integer you're initializing uppercase :)
