Page Totals

Question

I need the report in the following format,
Page - 1/3
..... 5
..... 5
--C/F 10
Page - 2/3
--B/F 10
..... 15
..... 15
--C/F 40
Page - 3/3
--B/F 40
..... 25
..... 25
Report Total 90
When I used the default facility of page totals the results were as below,
Page - 1/3
..... 5
..... 5
--C/F 10
Page - 2/3
..... 15
..... 15
--C/F 30
Page - 3/3
..... 25
..... 25
--C/F 50
Report Total 90
Then I used formula column to assign the values to variable and the results were
not satisfactory.
:Variable := :Variable + :Current_Page_Total;
With this I was able to get C/F but I don't need it on the last page as there
will be report totals there and it displays at the end of page so after report
total. I don't need B/F on first page and C/F on last page.
I hope the problem is not clear and if still any query the please.
Thanks for your time.
C/F = Carried Forward
B/F = Braught Forward

It sounds like you want to be able to determine if you are on the last page. If you are, you want to prevent an object being displayed.
A common way of doing this is to have a total count summary column (cs_total) and a running count summary column (cs_running). When :cs_Total = :cs_running then you know you've finished the report and can use a format trigger to hide the last "C/F" value.
The problem with this approach in your case, is that it will only work for objects in the body area. Since all margin objects are printed before the body objects, you can't base printing of margin objects on what happens in the body of the page.
The following isn't trivial to do but may give you a workaround for this constraint...
One way around the issue may be to place the "CF" object in the margin but move it so that it overlaps the body area. (Margin objects may exist under any point of the page. They don't need to exist outside of the thick black line). You can then place an opaque boilerplate object in the body on top of the "CF" field. This opaque object can be turned off except for the last page. This effectively blanks out the "CF" field on the last page.
The trick to make this work is to create a fixed sized frame for your body values (except the opaque frame). This fixed size frame should be the size that you want your body page to be - which will not be the complete body area so re-size the margin if required. You can then place the opaque boilerplate after this fixed size frame so it covers the "CF" field.
