[Zope] Selection property

I am a newbie trying to set up a selection property with a python script. I call folder_obj.manage_addProperty ( 'prop_name', 'VALUE', 'selection', **but how do i add the list** ) and also try folder_obj.manage_addProperty ( 'prop_name', list_here, 'selection', 'select_variable=one_of_the_list' ) I have a list in my python script. Should i reference the list from a zope path. Drew
