Hi,
A page, of paper, is not a known element in SQL, it is NOT a "group"
break recognizable through a change of data. You have to make the summation
yourself. The general way is to initialize a report variable to 0 at the top
print event, make the cumul at the appropriate detail print event, then, at
the footer print event, display it inside a text control or a label caption
you would have designed at that effect.
Now, if you plan to do it for a FORM, that is even worse, since it
clearly depends of the size (user re-sizable? ) form, or the number of
records actually displayed.
Hoping it may help,
