global.subscribe("radius", RadiusChanged); must be declared from an open document. You get an error in a folder level script because it runs before a document is open. Remove it from the folder level script and put it in a document level script.

That shouldn't matter. It appears like that in the Reference and it works from the Console, just not from a folder-level script, not even if you place it in a trusted function. It seems it can't be used in that way.
