I think that is because you forgot to close the script tag using </script> just after the function
Try debugging your source and check this:
var a, s = document.getElementsByTagName("script");
a = document.createElement("script");
a.src = "http://www.luminate.com/widget/async/11c0dab0ce0/";
which I suppose to be closed using </script> before </div> but seems not.
I haven't checked all the coed validity however.
