AttributeError: 'list' object has no attribute 'g_s'

[ndc85430]

There's a lot of code there and I don't feel like debugging it for you. At the very least, the traceback tells you on which line the problem occurs. Why are you trying to access some attribute on a list? Do you not expect the object to be a list? Work backwards from the problem and figure out why you're getting the list. If you do expect the list there, what are you trying to do? Access that attribute on each of the items, some particular items, ...?
