Hello Scott, There is a jquery error on your page caused by the superfish.js file. It seems this script is written for an older version of jquery and our extension uses the latest one. This error causes the accordion not load properly. As for inserting the accordion - this should be done through the Insert Panel and through the Top Menu named Insert...
Could this also be causing the insertion issue? (DMX Accordion will only open by using the icon in Dreamweaver's header menu and NOT by using the Insert > DMX zone > DMX zone Accordion. The latter method produces nothing.
