Are you using the brackets in the set of parameters for the morris function?

I think the debug message is telling you that you can't use brackets
in the tell function for the y=[] part.  Brackets in Python are lists.
 Alternatively, maybe M in your example is a list?  Either way, it
looks like you need to pass some other data structure than a list to
the tell function.  Sorry I'm not familiar enough with this to give
you a proper example, but hopefully this gets you started.

Best,
Mike
