I'm using Dustin Diaz's Sweet Titles scripts on a website built on the Big Medium content management system. http://www.kirklees-college-business-training.co.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?
