Grid and ruler origin puzzler

[grapher]

A WD6 newbie, I am trying to resize all pages on my new website but each time I try it I get the error message saying "The Grid and Ruler origin you entered was invalid." It goes on to identify what protocols have been contravened but I haven't a clue what it all means. A search of the help file has not turned anything up. If I resize the pages by dragging the frame lines around my page and then preview in my browser, the top of the page is chopped. Help please!!!

See attached error panel jaypeg

You may have added an amount to the existing page size rather than replace the existing size.

You should resize your pages in Page Options > Page Size. Right click on an empty portion of the page or pasteboard area and select Page Options... > Page Size. And you can opt to make all pages the same size or not.
