I’m working on a project that requires a title in italics (which can line wrap) followed by a description below that is indented (which can line wrap) followed by leader dots and possibly numerous page numbers separated by commas (right justified margin). When using single page numbers, I’m close to what I need, but multiple page numbers reset the margin and are indented incorrectly. I’ve uploaded two word documents, one with single page numbers and one with multiple page numbers (which has the indention issue).
I’m apparently missing something as I’m unable to achieve the desired results. I’m hoping someone in the community can help me get on the right track.
