    Question Trying to fix a YQL statement - Newbie needs help!

    Hello I am new to programming so please bear with me as this may be the stupidest question yet!

    I am trying to pull data through JSON from yahoo finance pages with the following code. When I run the code in the YQL console it throws the following error.

    THIS IS THE ERROR:

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

    I have attached the source XML file as a RAR file for ease of reading in dreamweaver or some other editor.

    Any help would much appreciated.
