1) Script Title: ddaccordion

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex17/ddaccordion.htm

3) Describe problem: I am able to successfully use the ddaccordion script, however I want to use it multiple times on my site, with different persisted states. Here is a link to my current implemtation of it: http://www.uky.edu/DistanceLearning/redesign/faculty/

I want each of the three main catagories (faculty, current students, and future students) to have different persisted states. I have been trying to hack the script to change variable names with no success. I even have different instance of the script in different folders. Is this possible?

Thanks,

Calvin

the headerclass: name is used as the cookie name

if each of your pages used a different name they will use different names

or
