Obscure Object Referencing

Yes indeed, it references the datagrid on the currentCard! If there is no such object on the current card, then even if there is one on another card that is not the currentCard, it throws an error, as you would expect! 

That is actually quite cool.

Apparently, even though the owner of the datagrid group is the card it's on, this doesn't matter to the parser! I wonder what would happen if I had another card with a datagrid with the same name on it, if it would reference that datagrid if it was the currentCard of that stack, or if it would reference the first datagrid in the stack with that name? I think I'll give it a try!
