Note that "Cookbook.", "Main.", and "NoSuchGroup." aren't valid
pagenames, so they can't be used before the '$GroupHome'.  Try instead


The key is that what comes before the $ has to be a valid pagename
in the group you want.  (It doesn't matter if the page exists, just
that it be a valid pagename in the desired group.)

In a pagelist, the template uses  {=$GroupHome}  and the '=' is
always replaced by the full name of the current page in the list.
Since this is a valid pagename, it works.
