They are part of the spread which is the parent of the page. Exactly how the hiearchy works here changed with CS5, so please be specific about your version if you need more information.
Sorry I should have mentioned I am using CS5.5
OK, so where are you stuck?
If you have a variable, say, page, that is a particular page, where page.pageItems is all the items on that page, then page.parent.pageItems will be all the items on the spread, which includes the pasteboard surrounding it.
Yeah that will do it! Thanks again!
