InfoPath Dev

I am able to retrieve values out of my forms from the task pane in InfoPath 2003. However, I am having difficulty getting it to work in 2007. I get the error "Reference to undeclared namespace prefix: 'my'."

Here is the code I am attempting to use:

// Get a reference to the XDocument object for the InfoPath Form.

XDocument = window.external.Window.XDocument;

var bb = XDocument.DOM.selectSingleNode("/my:myFields/my:field1").value;

Thanks to another online expert I was able to get the answer.

XDocument.DOM.setProperty('SelectionNamespaces', 'xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2007-09-27T16:18:33"' ); //The namespace for "my" path can be found in the myschema.xsd file.

var bb = XDocument.DOM.selectSingleNode("/my:myFields/my:field1").value;
