I have a support request form in Infopath that uses a category and subcategory look-up to other fields. I want to limit the subcategory column to choices that only relate to the category column. When I use something other than ID in the infopath form, I get "Only positive integers allowed" error. When I chose the ID column for the value, it works but only returns ONE field from the subcategory choices, not the entire list of subcategories related to the choice in the category selection. Any ideas on how not to use an ID field as a value in an infopath form? Or how to make the ID value return all my choices?
Thanks for any help.
