Need some help with a script

I have a problem here

When coding in Python, I get this error :


Traceback (most recent call last):
File "exl13.py", line 3, in <module>
script, first, second, third - argv
NameError: name 'script' is not defined

Here's the code : pastebin.com/NYek4iAF

Am I doing something wrong?
