XML: Assigning extracted properties - Overflow

[thedoc1]

I am working on an XML file for the NCUA program. The XML program comes with a complex XML schema. I am writing an XML file that is getting a Assigning Extracted Properties - Overflow error when importing the file into the NCUA software. I think I am just making a mistake in the XML file.

Here is the schema:

<?xml version="1.0" encoding="UTF-8"?>

here is my XML file

<?xml version="1.0"?>
<Transmission IsValidated="true">
<CreditUnion CharterName="BUFFALO FIRE DEPT. FEDERAL CREDIT UNION" CharterNumber="24068" CheckDigit="1584" Region="1">
<Cycle CycleDate="2005-09-30" UploadDate="2005-09-30" Form="5300">
<Account Name="A887Z" DataType="@" Value="Something"/>
</Cycle>
</CreditUnion>
</Transmission>

Any thoughts?
