Links between two workbooks are common and useful. But multiple links where values in workbook1 depend on values in workbook2, which links to workbook3, and so on, are hard to manage and unstable. Users forget to close files, and sometimes they even move them. If you’re the only person working with those linked workbooks, you might not run into trouble, but if other users are reviewing and modifying them, you’re asking for trouble. If you truly need that much linking, you might consider a new design.
