I'm not quite sure what you want to do, but I have a feeling you're 
mixing modes. Remember that to Zope Javascript is just text, and that to 
Javascript (aka a browser) Zope is not visible at all (unless you use 
XML-RPC).

Do you mean to define 'info' as a Javascript variable? In which context 
should it be global?
