The question actually got answered on the tutor list. Please accept my
apologies for not updating this list. Thank you for the concern. The end
result was the error I received is correct. What I eventually did was pass
the instance of my parent class (self) in addition to the parent root
instance. This allowed me to make a function calls on my parent class
instance. I'll post my final code for comments when it is completed.
Thanks for the concern.

Has no one answered Mr. Faulconer's question? My impression is
that it's MUCH easier than he's making it, but I'm not in a po-
sition to address it any time soon. I sure don't want him
thinking that we're unresponsive or that Tkinter is difficult,
both of which I know to be false, with occasional exceptions.
'Anyone comfortable with PMW have time for this?
