[Zope] attribute-less object(assign or del)

Module None, line 45, in copy_of_stats_output_branch

Line 45


for j in self.sql.sqlGetStatDetailsSum(date1=i.date, branch1=i.branch,
category1=i.category, timeCheck1=k):

              if str(j.sum_renewals)== 'None':
 line 45 -->     j.sum_renewals = 0
              elif str(j.sum_registrations)== 'None':
                 j.sum_renewals = 0
              elif str(j.sum_hours)== 'None':
                 j.sum_renewals = 0
              elif str(j.sum_reference)== 'None':
                 j.sum_renewals = 0


When I have values returned by the sql call it works fine but as soon as I
get to a field that has a 0 in it then I get an error...

As far as I can tell I'm doing the assignment correctly ... what's wrong
here?
