Page number choices dimmed or greyed out in Page Layout mode.

Dear Mario: Thank you for your attempted assistance, but I'm afraid your instructions do not work. I have already attempted to change the starting page number by placing the page number in the footer, as I said. I have also tried the same with a text box into which I have inserted the page number. The controls that would allow me to adjust the starting number are DIMMED OUT. I cannot use them. That is the problem. In the page to which you directed me, there are instructions to do this, but they are only for a WORD PROCESSSING document. I do not have such a document. Mine is a PAGE LAYOUT document. Please see the attached screen shot and you will observe that these instructions (Step No. 1) apply only to a WORD PROCESSING document. I am trying to figure out how to do the same in a PAGE LAYOUT document. That is my question. Do you know how to do this? Do you know how to create a SECTION in a PAGE LAYOUT document? Do you know how to make the controls UNDIMMED in a PAGE LAYOUT document? If so, please let me know. I hope I am now being clear about the problem. Thank you.

Thank you for your help. I finally figured out the problem and how to solve it. It has to do with the fact that I have the pages of the book displayed using the "facing page" feature. I was unable to control when the page numbering controls applied to the lefthand (verso) or righthand (recto) page. Via trial and error I learned that the controls apple to the leftmost and topmost page. So by resizing the window so that only the recto page was visible, the controls became undimmed and I could adjust the page number format and the starting value. This maneuver did crash PAGES the first time I tried it because I did not allow sufficient time for my changes to populate my 320 page document. But once I allowed for that, it went smoothly. I am attempting to avoid using InDesign or Quark because I truly like the PAGES interface. If you encounter this issue again, you might ask if the "facing pages" feature has been invoked. Thanks.
