Unwanted Tiled Pages in Publisher 2007

Every document/flier I create in Publisher 2007 that is above 8.5” x 11” page
size is being tiled and I want it to be just the single page in the size I
have selected 11" x 17". I have just tried to follow instructions from a
previous post "Choose File, print, re-set the page size to 11 x 17 on this
screen" but I do not have the option of choosing 11x17 or "tabloid" as it's
called in the Blank Page Sizes Window. Would someone please help me with
this? I have used the "publish as PDF" add-on as suggested in a previous
postings as well, in an attempt to send a flier to a commercial printer to
create full bleed fliers. Should this do the trick? Thanks very much!
