@wayne.anderson you can’t use our minecraft editor from the browser. you can look at and edit code, but your programs will not run.

if you want to run the code, you need to do so from within the minecraft education game. you can open the code editor by pressing “c” while inside a world

I know how use MakeCode in the game. The screen with the red button is what my students see when they try to process block coding in the Minecraft game.
