i have a repeating frame that prints on every page for a product code. But when on page ends the info associated with that product code is truncated and not overflowed to the next page.On the next page data with the new product code is displayed. I want the data for one product code to be continued on the next page if it does not fit on a single page. The values are as: repeating frame vertical = variable horizontal = variable page protect = 0 print object on = first page base printing on = enclosing object for the outermost frame which encloses the repeating frame: print object on = last page base printing on = anchoring object end of layout section = yes rest all the values are same as the repeating frame
