In just assumption, I assumed you realized I put everything except the
struct definitions in a function.  After I learned I couldn't assign
values out of a function, I fixed that problem.  In all truth, my
problem most likely lies with a problem in the way I have assigned
values throughout my various structs.  The important question within the
previous code snippet was the possibility of using assigning structs
within structs.  I'm sorry if I didn't make it clear that the code
snippet was in a function.
