Attempting to build a cascading menu in SharePoint 2010, using info path. Basically I have 3 menus as shown below. All 3 menus are tied to a sharepoint list of info. – when I select that, menu 2 populates based on an infopath filter/data source I set using this link and it works fine! Each would populate on the prior level.
What I'm trying to do now is populate a third menu, based on info in the 2nd menu. No matter which way I try and filter it, its blank. Can someone guide me in the right direction?
