Thank you, Matt. Dynamic is a tricky concept. I've yet to wrap my head around it.

I did end up with a working version of the game through a similar solution to yours, though I still have the Dynamic in the last line. Your solution is cleaner, so I won't post mine. I'll go back and see whether I can clean my version up.

Thanks again,

Mark

Thanks, Murray, for the comment. The game pulls its taxonomic data from the Wolfram curated data. That way if classifications change, the game changes too. Currently the kingdoms that the player has to choose from are animals, chromistans, bacteria, viruses, archaeans, fungi, and protozoans.
