The details on the right are too small to see if they show three different amounts or the same data three times.
In preview mode, FileMaker assumes that you will print the entire found set with the "Records being Browsed" option. Thus, every record in the found set is previewed and clicking the "book" control moves you through the different pages (not records) of your previewed report. This does not mean that printing from this layout will give you three pages when you print with the "current record" option.
What's undetermined for me is whether you have three rows of data here that need to be combined in a single page or you just need to disregard this preview and print it. If the three pages should really be one page, you may need to select "view as list" for this layout before it combines the data on a single page.
