Hi Stuart,
Thanks for letting us know about this. There is a current issue with our site that will not allow users to save "fixed price" or "store items" item details profiles without filling in the "Buy it Now" price field. This issue is on our list of things to correct but I'm not sure when we'll be able to get that work done at the moment.
If you are indeed being affected by this problem, you should be able to work around it by entering $1.00 in the "Buy it Now" price field within the item details profile prior to saving. If you make that adjustment, I suspect you'll find your content is saved properly.
If the nature of your problem is different than what I have described above, I recommend contacting our customer support team using the web form on the following page of our site:
