Crystal Report Paging

Question

Hello

I have two sub-reports added in the header of the Main Report. 

Each sub-report has a header that has to be repeated on each page. To do that I had added a formula whilereadingrecords and added a group on it. Now I can have the header in all pages. But there is no such provision for footer. 

And I want page number in footer. 

As a work around I tried adding page number in header. Now, the Page number is visible but  the problem is that page number on subreport is not continous. the page number on the second subreport starts with one.

eg  main report has 10 pages

subreport1 start with 1 ends at page number 4

subreport2 again starts with 1 and ends at 6

I want subreport1 to start at 1 and subreport2 to start with 5

also if any one can tell me how to put them in footer
