I don't think your code worked at all.... The problem is that octave 
thinks that Problem72.m is the element "m" of the structure "Problem72".
As the variable Problem72 doesn't exist, octave doesn't know its type.
A clearer error message is probably in order here though.

You forgot the quotes to tell octave that it is in fact a string.. Try
source("Problem72.m") and it'll work properly this time. Or alternatively
you can do 

octave:1> mark_as_command source

and then do

octave:2> source Problem72.m
