This is NOT a page x of y problem since there is really only one page.

The simple way is to have your form with a Page X of Y footer and have the 30 pages. You could do this by having the first line of your form formatted to have page break before and selecting the entire page except the last paragraph mark. Insert a bookmark with a name. Then at the end of the page have 30 REF fields cross-referenced to the bookmark. For instance, I named the bookmark "tester" and then pressed Ctrl-F9 to insert a field. I type the bookmark name of tester. It looks like { tester }. I then copy and paste that field for the desired number of pages (29 fields). When I go to print, I have 30 pages and the page x of y footer gives the correct count.

This will give you your 30 pages but if you change anything on that first page it will be reflected in the other pages.
