how to custom page size setup in pages '09
I need to have my page set up in US Postal size (6 x 9 inches) to enable me to upload a manuscript for publishing. However, when I choose page set up, custom set up, the areas which require the sizes to be entered are greyed out and unable to be typed in. Any advise appreciated.
