Problem with Editor folder


When i try to compile my game i get this error:
“Error building Player because scripts had compiler errors”
I found a solution here: Error building Player because scripts had compiler errors - Questions & Answers - Unity Discussions

But i don’t know why it doesn’t work for me(
I’ve created folder and put script into it, but error still appears.

Looks like an error in a script. Is that CellsEditor script the only one?

If so, open it up in Visual Studio and ensure there are no problems with it
