Hi Anthony,
Thanks for your response. I made the recommended changes, and it got rid of
the "Uncaught SyntaxError: Unexpected token < " error.
I'm now just getting the "Uncaught ReferenceError: data is not defined ".error,
and of course nothing displays from the document.write call.
Thanks again
- Lyndon
