MapLocation.cs(9,52): error CS1525: Unexpected symbol `is outside the boundaries of the map.'

Question

Following the vid and at the point of compiling and running the program.  In the vid, Jeremy is able to compile and run with the exception message displayed in the console.  I'm running into this compiler error, and I can't figure out how to fix it.  I googled the error CS1525 and read over the msdn doc, fiddled with the code some, but I'm still not able to compile without this error.  
HELP!!  
My code in MapLocation.cs: 
namespace TreehouseDefense
{
  class MapLocation : Point
  {
    public MapLocation(int x, int y, Map map) : base(x,y)
    {
        if (!map.OnMap(this))
        {
           throw new System.Exception(x + "," + y " is outside the boundaries of the map."); 
        }
    }
  }
}
Console error:
treehouse:~/workspace$ mcs -out:TreehouseDefense.exe *.cs && mono TreehouseDefense.exe

The problem is in this line:
csharp
throw new System.Exception(x + "," + y " is outside the boundaries of the map.");

You are missing a + between y and " is outside the boundaries of the map.". Without that + c# has no idea what you want it to do with that string. That's why the error message is complaining about an unexpected symbol.
