Without seeing the form with the XML resource file I can't begin to guess. Have you opened the XML in a text editor and searched for "#N/A"? I think in another post, you talked about creating this XML from Excel - #N/A is a common error in Excel, like when a VLOOKUP doesn't return a value. In the last version of the form I looked at, your cascading dropdowns weren't in a repeating group. Has that changed?
