grassy scenery not loading

I set everything up like the absolute beginner’s guide says to in the manual, and it works as far as the grey screen, but when I try to load the grassy scenery in the “hello world” tutorial, I get this error message:

Does anyone know what is going on here?

the node is called "render " .not “renderer” … rename it and it should run

Ok, that did it
