    Help with dbm TypeError

    I am writing a web application for mod_python that catalogs my home
    (book) library. For now, I am using the Python dbm module to store
    string representations of mod_python's req.form (using the
    mod_python.publ isher handler) using unique IDs as keys. In the .db
    file, there is a key 'next' that holds the next key for the next form
    submission. A TypeError exception is raised though when I attempt to
    increment the 'next' key. This only occurs in mod_python.

    This code...

    self._db['next'] = str(int(self._d b['next'])+1)

    raises this exception....

    TypeError: string indices must be integers
    [color=blue][color=green][color=darkred]
    >>> y = dbm.open("Test" ,"c")
    >>> next = 0
    >>> y['next'] = str(next)
    >>> y['next'] = str(int(y['next'])+1)
    >>> y['next'][/color][/color][/color]
    '1'[color=blue][color=green][color=darkred]
    >>> y['next'] = str(int(y['next'])+1)
    >>> y['next'][/color][/color][/color]
    '2'

    I do not understand the cause of this exception. I am using Python
    2.3.5. Any help would be greatly appreciated.
