InfoPath Dev

I have a structure as follows in a secondary datasource in an infopath document Sections Questions Options I have a repeating section of sections with a repeating section nested inside it Inside that I have a combobox which is bound to options. I want to filter the combobox by a field within the question containing it. Instead it is returning all the unique options regardless of question

This is a very common request and there are numerous posts on filtering dropdowns. Please try our search: http://www.google.com/coop/cse?cx=003654972516704994317:4j0mji2l1rq
