Reset count (running total) after pagebreak

[bradford]

I created a report that summarizes students on different buses. (It's for a school attendance.) I find that no matter how I define a calculation I am still stuck with the same result---the same result I get when I add @@ to the layout, just numbers that go up that don't restart. I want to see a running total of each student on the bus. When the page breaks for the next occurence I want to have the numbers reset. I have searched the web as well as this forum for an answer. For the record I don't think it's an easy one.

If you have a Bus_ID, then why not use a SelfjoinOnBusId, with your Bus_ID at both sides of a relationship within the same file.

Then c_countPerBus = Count(SelfjoinOnBusId::Student_ID*)

* or any other field you have.

Can you dumb it up? Not sure what you mean. I tried what I thought you said to do but no go.

Ugo, I like that example. It really puts in some cool things about ID# that I didn't know you could do. Thanks.

since I am on the subject, I have made a report for attendance. It is sorted first by day, then time then class_id. My problem is that it is breaking the body when the page finishes and continues on the next page. Is there a way to not let is break it? so if the body doesn't fit it will continue it on the next page? I know there is the part function that page beaks after each occurrence but that isn't what I need. If I did that, then I would have 20 pages for a single day. A little too many sheets for my books. Any advice would be helpful.

Thanks for everything.
