That works now, but I get a error with instruction:

htmlcode += view.index["childInfo"] <--
    
  
traceback:

  File 
"/home/florian/Desktop/zope/lib/python/CS/centershock/browser/skin/views.py", 
line 41, in getHTML
    htmlcode += view.index["childInfo"]
TypeError: unsubscriptable object

The macro is existing. See also my previous posting.

Thx,

Florian
