I think you need to explain more clearly what you're doing with the document. The code I posted has no effect whatsoever on anything you type into the document or your userform - all it does is to ensure that clicking on CommandButton1 doesn't keep adding new content.

If your document is misbehaving, I can't really comment on that without seeing it. Can you attach a document to a post with some representative data, including your userform (delete anything sensitive)? You do this via the paperclip symbol on the 'Go Advanced' tab at the bottom of this screen.
