Coming up empty

This module strikes me as a good idea, which I'd like to share with others. However, I haven't been successful in getting it to work.

I added a field named description, of type Text - Text field
I tried both Plain text and "Filtered text (user selects input format)"
I set the php_value memory_limit 28M in .htaccess.
I turned off a number of modules.
I selected CCK Node Type of Swim Group
The Copy to Field is field_description (there seemed to be an extraneous option named field_select, as well, perhaps coming from an integer field...)
I'm using the latest version of cck for d5.

Instead of returning to the page, I get a screen like this:
(Also, when I check the swim_group content type, the Description field is empty.)
