InfoPath Dev

I have 3 lists Category, SubCategory, DocTYpe that Cascade in the same order. Each subsequent list has a lookup coulm to the parent. I have it working fine in Sharepoint with SPServices cascading drop downs. I want to use the dropdowns in the DIP for Office Docs. I am setting up the DIP tempate in infopath using the 3 lists. By default they use the ID for value  in the dropdown lists. I am trying to set a filter on the Subcategory list as follows "Category is equal to @Title[@ID=CoAgCategory]" Category is the lookup field in the Subcategory list. I am trying ot set Category to the display name of the dropdown list value. Any help would be great

Hi - any chance you'd attach your form to the Options tab in a reply? It would probably be easier for me to give you a hand if I could see what you were talking about. :-)

I go it working using this tutorial:
