The script is actually working successfully (tested at hurl.it). But in tiggsi even though the script does eveything it should, I don't get the response back that I do at hurl.it so the code to run on completion of the post doesn't run.
However, the post shows up red on the firebug console and shows this - I wonder if there is some problem with receiving the returned data on your server?
