Instructions for properties in CX_props_popup.

Use the Properties tab to adjust the attributes of the 
  rollover PopUp text that displays when you rollover each
  event displayed on the calendar.  Just check off the ones 
  that you want to show up.  
Other Properties:  These values represent the metadata that are stored in
  the portal_catalog for each event.  If you want to display other information 
  about the event that is NOT in the metadata by default, you simply tell your
  portal_catalog to collect that metadata, then modify the CX_props_macros
  page template to read it into your popup text.  
There's also a howto on the CalendarX.org website that explains how you 
  can add other attributes in more detail.
