Hello, LotsaGrit.
Let's start off by checking the helpful steps in this article: Save and name a document in Pages on iPad - Apple Support. The "Save a copy of a document" section gives instructions:
- "Open Pages, and if a document is already open, tap Documents in the top-left corner to see all your documents.
- Touch and hold the thumbnail of the document you want to copy, lift your finger, then tap Duplicate. The duplicate appears with a number appended to its name.
If you don’t see the document you want to copy, try searching for it, or tap Browse or Recents at the bottom of the screen. For more information, see Find a document."
Let us know if we can help with anything else at all or if this doesn't settle your issue. Thanks and have a fabulous day!
