This should be a relatively simple question for HyperCard gurus...
How can I check if a card exists? What I need is something like:
  a button's script contains

     if card child is empty [ie hasn't been created/visited yet] then
          doMenu "New Card"
          do getNote (child)
      else go to card child

where child is the card name of a lower card in a hierarchical structure,
and getNote is a function that grabs it from the outside world.

Any suggestions/help is greatly appreciated!
