Maybe a long shot asking here but need to help with InfoPath and SharePoint.

I have three SharePoint lists:-

ListCountry
CountryName : Single Line of Text

ListCity
CityName : Single Line of Text
RelatedCountry : Lookup [ListCountry:CoutnryName]

ListBuilding
BuildingName : Single Line of Text
RelatedCountry : Lookup [ListCountry:CountryName]
RelatedCity : Lookup [ListCity:CityName]

Now I want to setup an InfoPath form for the ListBuilding list so when I add a new entry I first select the country, then city, and then populate the building info.

The form can access both of these lists fine via drop downs however I’m struggling to setup a filter so that once I select the country only the City’s within that country are visible from RelatedCity lookup.

I know this is possible via InfoPath but can’t get it working, any pointers/ideas?

Many thanks
