What is wrong with this?

Chainreading, a book-tracking site I find utterly indespensible, offers various codes you can put in your websites that will keep a constantly updated list of what you're currently reading.

I've been trying to put this into my user info, but it does nothing. When I view the page after pasting it in, you can see neither the source code nor what it's supposed to produce.

Does anyone know what might be the matter? Here's exactly what the site says:

This script displays the books you are currently reading in a little customizable box that can be displayed on your website or blog. To use this code, simply copy and paste the code below onto your website.

<script src="http://www.chainreading.com/scripts/reading/391?width=218px"> </script>

It's entirely possible that LiveJournal has disabled that code by policy. First off, it uses the <SCRIPT> tag, which can be used to embed a lot of nasty things. Secondly, the source of the script is not on LiveJournal.com, and a lot of sites don't allow scripts to be read from foreign sites because it can create security holes ("cross-site scripting").

I wondered if that might not be the case. =\ Oh well.
