Oh, I found something about in the archive!

I'm new to ConTeXt and try to use the module typearea (https://modules.contextgarden.net/cgi-bin/module.cgi/action=find/name=typearea).
But the example doesn't work:


I got:

A number should have been here; I inserted '0'. (If you can't figure out why I
needed to see a number, look up 'weird error' in the index to The TeXbook.)
mtx-context     | fatal error: return code: 1

Line 89 in the module should be the problem. But how can I solve it? I think some lines in the module should be commented out. (An example directly in the module?)

I thank you for any hint.
