MS Error Help?

[Lord Leoric of Wercheg]

Traceback (most recent call last):

  File "C:\Python26\lib\string.py", line 517, in replace
    return s.replace(old, new, maxsplit)
AttributeError: 'list' object has no attribute 'replace'

I added a few items, checked for missing [,]() and wrong spacing but I always get this.

EDIT: Nevermind. Fixed it.
