First, thank you for your response...please forgive me for not clarifying as I did have the second as a repeating table, currently My Data Source looks like this:
Geocoding
Locations (Group - Not Repeating)
Regions (Group - Repeating)
txtRegion (Text String) - Either North, South, East or West listed within SharePoint List named "Regions" within a single column
State (Group - Repeating)
txtState (Text String) - All US States each associated within Region (see above) in a SharePoint List named "States" within two columns "Regions" and "State"
I decided to not use an .xml document and instead attempted to use two SharePoint lists as described above as my Receiving Data Connections. I am very close to getting this work properly; however, when I applied a filter to my secondary States Data Source (specifically the Regions) it works fine for the first filter selection but afterwards includes States from previously selected Regions. For example if I defined East as the Region I would be presented only with States that fall within the eastern region on the first selection. Let us say I selected New York from the Easthern and then added another Region, say South....well now I not only see Southern States within the States drop down but I also see Eastern states because New York was previously selected. I've tried using "current()/my:GeoCoding/my:Locations/my:Regions/my:txtRegion", while the fomula is validating it doesn't work...I don't get anything in the States dropdown when I attempt to use it. Any assistance would be appreciated...
