[GoogleCodeExporter]

I have done something like this many times already without any problem.  Based 
on
what I see in the error message, it seems that a quantity or unit cost value 
doesn't
have a value assigned to it.

I have modified the code so that, for now, if either the quantity or unit cost 
of the
item being purchased is not set, the program will not attempt to include it in 
the
total cost.
