Resetting page number with new page after feature turned on

If I am using a new page after feature in a group footer, how can I reset the page X of Y after each change of group?

For instance, I have a employee grouping with 2 pages of information and in each page it should ready page 1 of 2 and page 2 of 2. But instead it reads page 1 of 36 and page 2 of 36 (36 is the entire report). How can I reset the page numbers?

Thanks in advance,

Z
