in reply to Re^6: Possible for Map to create Hash of Hash?
in thread Possible for Map to create Hash of Hash?

Well the OP explicitly asked for HoHs and said " To create a hash that will allow me to determine if a store has a product I can use: "

I'm no native speaker, but for me this also reads like "if a store has products at all" which is quite complicated with a flat multi-dim hash.

To me it sounds like he just needs a store/product lookup and assumes that he needs an explicit HoH...but it is somewhat ambiguous, and things around here are not always clearly written, so let's just throw both solutions out there and let'em pick.
