Can't edit pet listing

Annoyingly this page had an error and I have to start all over again! Anyway, I lengthened my listing the other day because all my baby guinea pigs hadn't sold yet, and I went to edit it (reduce price etc) and I got to the last screen of editing, and clicked next and nothing happens. Does this on every browser and even different computers so is definitely a trademe issue. They say on the same page that they are updating some of their systems and to tell them what I think but those links don't work either! Extremely frustrating as it's close to Christmas and I don't want to get stuck with extra guinea pigs over January! Anyone else having this problem?
