Just went through the process again. The problem with the code on the page is where the anchor for the accordion is placed. Once you hit next on the delivery method, is scrolls you down to the top of the Payment Info FIELDS; not the top of the Payment Info SECTION where the Payment Plan info is.
Front Gate has shitty (lazy) coders, plan and simple. This is also the reason people could direct link to by-pass the waiting room.
