Well, I figured it out. You have to delete history on the object. Why doesn't the friggin' help faq tell you this?! Do you know how long I've been trying to get this to work?! My gosh. I figured this out when I decided to read the script editor to see the details of the error I was getting, which is something I rarely do. I was going to delete this thread, but I apparently don't have the authorization to delete my own posts.
