Hi Athena,

From the Insert Ribbon, click Page Number|Bottom of Page, scroll down and select one of the 'X of Y' formats. Then, if the default
style doesn't suit your needs, click 'Home and expand the 'Styles' tab. Now click on the drop-down arrow for the 'Footer' style and
modify it to suit.

Cheers

In addition to what Macropod told you, this will work as well...

Instead of choosing one of the Header or Footer commands, select the Page
Number command. You can then choose Top of Page or Bottom of Page, and
within that gallery there is a selection of Page X of Y.

Since the numbers are bolded, you can format the numbers for not bold, and
then save the selection as a New Building Block, which will enable you to
quickly re-use the format again at a later date.

Hello,

  In Office 2003, it was possible to define footer/header with selections
for page numbering. In 2007 version of Word, you can only choose styles for
header/footer and it seems it is not possible to change/modify a style. I
want to choose a footer style but I want to have Page X of Y of styling. How
can I do that? thank you.
