can't figure out syntax prob

[python newbie]

Can someone please tell me know what is wrong the code below. Whether I try
to just execute this class definition in IDLE, or include in a py file that
I attempt to run with python.exe, I get the error at the bottom.

In case this formatting gets messed up after posting, the carrot is pointing
at the second parenthesis.
I saw in Quick Python book, that I can define an __init__ function with more
than argument.
Thanks

class FileGroup:
  sourceDir = ''
  destinDir = ''
  frequency = 1
  recursive = False
  def __init__(self, fg)
  sourceDir = getSourceDir(fg)
     destinDir = getDestinDir(fg)
     frequency = getFrequency(fg)
     recursive = getRecursive(fg)

  File "OregonBackup.py", line 23
    def __init__(self,fg)
                                    ^
