The main problem I was commenting upon though is subtly different from understanding how to use NestedLoops.

Yes. I'd hoped my explanation might still help with the other problem (and help others understand the code)...

It's more a case of wrapping my brain around how to apply it to any given problem. I guess it is really no more complicated that coding a recursive routine and remembering [...]

Yeah, that certainly sounds like a difficult way to go about it. Instead, think of writing foreach loops. Does that help much? I could elaborate but I'd rather do that based on your response. I could go into how to write foreach loops but maybe that isn't something you need elaboration on. (:
