Liam,

   I've gone around this error by moving the two database functions (open and
close) into a separate module/class. Since that class is now imported by all
the other modules that need database access, I'm trying to learn how to make
a variable defined in one module -- the name of the database file -- visible
to the functions in the new module.

   This variable -- projname -- is local to the wxPthon text entry function,
global to the MainFrame class, and not a built-in variable. Therefore, it
is not visible to the openDB() and closeDB() functions in a completely
separate module. I'm trying to learn the python equivalent of C's 'extern'
declaration modifier.

Thanks,

Rich
