Need to add a non-table field to a card page

WantsToLearn

I have a card page with a lookup. I want to display a field from the lookup table on my page. For purposes of discussion, let's say my lookup is into the Item table and I want to display the matching Item Description. I defined a global var ItemDescription and decorated it with the [InDataset] attribute. I can add it as a field to the page field(ItemDescription; ItemDescription) and the code compiles, but the ItemDescription never displays on my page.

Am I missing something obvious here? Thanks in advance for any ideas and/or suggestions.

I forgot to set the ApplicationArea property. Once I set that, my field appeared as expected.
