Hi… Great.!.. thanks very much for the prompt reply! I’m not entirely sure what the server at the other end does… all I have to work with is a specification sheet which simply dictates the HTML Headers and XML content for the request. Talk about flying blind! 
I will look at the example you suggest and will update this POST with my progress. I am sure there are thousands of WIX users needing to do the same.
Cheers!
