Hello, all.

I'm attempting to create my first DotNetNuke module in C#.  I based my module (a parent/child database app) on the C# Survey Module example, and have enjoyed great success in adding and modifying both parent and child records.

However, when I go to import XML data (which I obtained from an existing PHP module and patterned after my DNN module's export file), I get an unextremely unhelpful "An error occurred during the import" message.  Additionally, I am returned to the "import module" dialog where the XML file is now listed twice in the drop down box.

Below is an excerpt of my XML data file:

<?xml version="1.0" encoding="UTF-8" ?><content type="Rga" version="01.00.00"><Rgas>
  <Rga>
    <CreatedByUser>???</CreatedByUser>
    <CreatedDate>???</CreatedDate>
    <Customer>???</Customer>
    <ShipToCustomer>???</ShipToCustomer>
    <Phone>???</Phone>
    <RgaNumber>???</RgaNumber>
    <IssueDate>???</IssueDate>
    <AcquisitionDate>???</AcquisitionDate>
    <DispositionDate>???</DispositionDate>
    <RgaParts>
      <RgaPart>
        <PartNumber>???</PartNumber>
        <QtyReceived>???</QtyReceived>
        <QtyRga>???</QtyRga>
        <Comments>???</Comments>
        <Action>???</Action>
      </RgaPart>
    </RgaParts>
  </Rga>
</Rgas></content>

Each RGA will have certain parent fields, such as customer info and dates.  Additionally, each parent record may include one or more "child" RgaParts.

Here is the IPortable members that I have altered from the C# Survey module.

        #region IPortable Members

            XmlWriter Writer = XmlWriter.Create(strXML, settings);

            // Outer Loop - To build the Rgas
            List<RgaInfo> colRgas = GetRgas(ModuleID);
            if ((colRgas.Count > 0))
            {
                Writer.WriteStartElement("Rgas");

                foreach (RgaInfo colRgaInfo in colRgas)

Can someone please clue me in on what I'm doing wrong?

Thank you in advance,
