It looks like you are using mootools to implement the ticker which uses:
instead of onload.
If you view the page in fire fox and check the error console,
you see the following:
Error: settings.newsLinks[currentItem] is undefined
Source File: bbc_newsticker.js
basically the list isn't being created before it is being used. you need to find a way to modify the script so that the ticker list gets created it is used.
