I'm using Dustin Diaz's Sweet Titles scripts on a website built on the Big Medium content management system.

http://www.kirklees-....uk/index.shtml

This displays attractive 'tool tips' on links - showing the contents of the 'title' attribute.

The scripts work well on the links I can control, but there are links within the site which I can't access in order to add a 'title'.

Here the scripts display an empty box.

I have no knowledge of Javascript, hence this question.

Is it possible to alter the script to not trigger a tool tip if there is no 'title' attribute in the link?

If so, could somebody show me what to do?

Many Thanks
