I know it may seem insignificant or blatantly obvious to some, but I think mentioning that the "page" and "story" check boxes as shown in figure 2-1 (pg.15) should be checked to make the data form appear would be helpful. I am a first time user of Drupal and the fact that my data table wasn't showing up had me perplexed (and triple checking my code against the book's) for a while. Part of the problem is I am working with a site a coworker (who is no longer available to talk to) made and they only have "story" content created on the site.
