Error CS1061

Hello, I am getting the following compilation error:

"treehouse:~/workspace$ mcs -out:TreehouseDefense.exe *.cs && mono TreehouseDefense.exe
Map.cs(19,20): error CS1061: Type TreehouseDefense.Point' does not contain a definition forx' and no extension method x' of typeTreehouseDefens e.Point' could be found. Are you missing an assembly reference?
Point.cs(3,9): (Location of the symbol related to previous error)
Compilation failed: 1 error(s), 0 warnings "

Here are my screenshots: https://w.trhou.se/wp92ss1cs7 https://w.trhou.se/psoa3lnbyo

Can anyone help me find out what I am missing? Thanks in advance

The fields in Point.cs are upper case and in Map.cs they are lower case - change in Map.cs point.X (to upper)

As Deyan mentioned, the names on line 19 of Map.cs are just in the wrong case. Here's that line corrected:

      return point.X >= 0 && point.X < Width && point.Y >= 0 && point.Y < Height;
