How can I fix it ???

        action='precondition' + oid_name

"referenced before assignment" means that the variable has not yet been declared. I will leave it to you to learn how to Google for the error message as these very simple error messages are already explained on many sites. If you don't already know, there are many beginner tutorials available http://wiki.python.org/moin/Beginner...NonProgrammers
