jomolungma,
Not sure how much help this will be but I did a lot of hunting before I finally figured out how to get my pdf combiner to work.
Now the way I do it is to start with a complete PDF that contains every possible page that could be included and have a check-box selector field to let users pick from a menu of pages to include. In this code behind I force all documents to use pages 1 through 3 as cover pages and page 4 (of "Main.pdf") is always the last page. After that, the pages are determined by which check-boxes are checked on the aspx page.
Not clear on how this relates to your project but I hope you might find something you can use.
Code:
