Crystal report page total problem...

Question

 am designing a report that requires that, for each page, the sum of a specified column is to be displayed at the end of the column before going on to the next page. For each page the total displayed should be sum of the column values on that page.

There is also a requirement that the same total at the end of the page be displayed at the top of the next page.

How do I achieve this?

example:

------Page 1------------
previous page total: 0
chq_amt
100.25
50.25
58.50
20.75
20.25
current page total: 250

----Page2--------
previous page total: 250
chq_amt
10.50
18.25
100.75
20.50
50.00
current page total: 200
etc.
