Everything was running smoothly...until it wasn't.
I've tried creating a new playground, but that didn't work. I think the problem is that I'm not sure what a developer edition is, how it is different than a playground, and how to create a new developer edition.
Many thanks for your help!

I appreciate your replies.
In the end, I just didn't follow directions.
In case someone else makes the same mistake I do, I've included a picture. I read the directions to "click in the blank space below" and assumed I was finished with the project. I didn't realize that I needed to insert the false value after "Is Null" as is pictured in the table and image.
