Please Explain This Error

   In my wxPython application, each notebook page is a separate module file.
I insert, update, and select records from the sqlite3 database in each of
these modules. Until now, python has not complained about opening the
application. But, in the module with the class 'modPolicy' I get this error:

   File "/data1/eikos/policyPage.py", line 60, in __init__
     self.cur.execute("select * from component where category = 'natural';")
AttributeError: 'modPolicy' object has no attribute 'cur'

   The offending line is in the __init__ method:

     natComp = []
     self.cur.execute("select * from component where category=natural;")
     row = cur.fetchone()
     while row:
       natComp = row[2]
       # get next row
       row = cur.fetchone()
     for x in natComp:
       polID = self.polTree.AppendItem(self.natID, 'x')

   Every reference to the open database cursor in the other modules is
written the same way, so I don't see what is broken in the above syntax.

   Clues greatly appreciated.
