Rick - When you say that you only see 1 category, are you referring to the cut & paste screen prints I posted above? If so, that's b/c I only used 1 plant as an example to see if this worked. And it is kinda like a subcategory, depending on how one's mind works.
I now owe zuzu an apology b/c when I attempted to undo my example, I hit delete or whatever. Guess that's for deleting an entry in the main plant database. Oops. Later I saw the little trashcan icon and I guess that's what I was supposed to use.
I think we're on the same page, so to speak, about the QR codes.
Again, thanks for your help.
