Hi Austin,
It took me a while to used to this new community page.
Just want to update you that I have solved this problem. It's nothing related with the coding. In the end, I found there is a hidden field with a special character "&" which is not allowed in XML. Thanks again for your suggestion. It really helps!
My following question is I don't understand why this filed is a XML field? If next time, I need to add a new field, from where and how I can avoid using a XML field.
Thank,
Ning
