Displaying XML data in Accordion panels

Wolverine68 · July 1, 2009

I want to extract data from an xml file, then display it in expandable and collapsable accordion panels. The XML data is displayed but the panels are not expandable or collapsable. No error messages, so I don't know why it's not working.

Code:

Made some changes but the panels still don't expand or contract:
