thanks for the suport. I attached the file to this post
I changend that v3 thing in the code and the xml name also. All error messages are in German, I don't know why.
I would appreciate if you can send me your email so I can send you the xml file. It's probably easier that way to find the concrete problems.
I took the map and the xml of WW2v3-1941 and changed it.
The plan is to split the Americans into Americans_west and Americans_east, ech with own income, own move order, own units and so on. In the end the should be two nations for the Allies like USA and UK.
however I made some mistakes as I get
SAXParseException: game: World War II v4 1941, line: 2464, column: 8, error: Element mit "Americans" ist im Dokument erforderlich.
but there are more error messages.
I need help.
I can send the xml to someone who is much more experienced in map making than I am.
