A little bit of ASCII art... *grin* 'x' is a typo --- you want to grab the
filename stored by 'in_file' instead.

The conceptual problem is between file names and file objects.  They're
different, so perhaps it'll make it easier to give them different variable
names:

  in_filename = raw_input(".CSV file name?  ")
  in_file = open(in_filename,"r")


Next time through, it would be helpful to pinpoint to us your problem or
bug; otherwise, it makes it much harder to find a solution.
