The report we have sent you has exactly two lists which are on separate pages. If a list is longer than a single page it will continue on a new page. However when the new lists starts (the second one) it will always start on a new page, i.e. you will have a page break.
Please have in mind that inserting page breaks randomly in the report is not possible (as stated in the previous posts). Inserting page breaks can be done if you have properly grouped your data. Then you will be able to set a page break before, after or before and after a new group. The example sent to you does just that - it wraps the two lists in a group so that they can take advantage from the group paging.
If your lists contain completely different data you may need to use a user function that returns your data source based on the group in which your list is.
