A couple of thoughts:
- Rather than a command button consider using a regular macro and a QAT icon stored in the document.
- Word does not really think in terms of pages, but rather bookmarks, words, and paragraphs within sections. Pages comes up when it is time to print and can change depending on the printer driver being used.
- Have you considered using AutoText? Automated Boilerplate Using Microsoft Word
What is it you are trying to accomplish by copying and pasting pages?
