python errors

Hello,

I'm working on mine final internship en thesis. And working for the first time with pythonwin.

I'm trying to make the python script work but i'm getting a lot of errors. I'm using pythonwin (2.6)

Traceback (most recent call last):

Is there anyone who can help me with this? If you need more information, let me know:)

Thanks:)
