report builder 6 (I know this is way old ...)

This is probably simple, but I didn't find a solution:

I've got a repeating frame containing a number of records. Below
there's a single frame containing  a totals line:

<record>
<record>
<record>
------------
<sum>

Now I want to ensure that the totals line never stays alone on the
last page like:

<record>
<record>
<record>
<page break>
------------
<sum>

It should alway be:

<record>
<record>
<page break>
<record>
------------
<sum>

Any ideas?

Thanks a lot,
Stephan
