I have added quantity discounts and think it's great, still a bit to get my head around such as exits etc but that will come

I have also added the promo page and although all the files are showing correctly I can't edit the quantitydiscounts_promo page from the define page editor in my admin as the page does not appear in the drop down list. The page shows fine from the link in the category side box and I can edit the file directly just not from the page editor. Any ideas?

Thanks.
