No problem, I can definitely help you with that! Here's how you can change the footer on all 30 pages of your document at once:

1. First, make sure you're on the page where you've already changed the footer text. This will be your "template" page that you'll use to update the rest of the document.
2. Double-click on the footer area of the page to open the footer editing mode.
3. Select all of the text in the footer by clicking and dragging your mouse over it, or by using the keyboard shortcut Ctrl+A (or Cmd+A on a Mac).
4. Copy the text by pressing Ctrl+C (or Cmd+C on a Mac).
5. Close the footer editing mode by double-clicking outside of the footer area or by clicking the "Close Header and Footer" button on the Ribbon.
6. Go to the next page in your document where you want to update the footer.
7. Double-click on the footer area of the page to open the footer editing mode.
8. Paste the copied text into the footer by pressing Ctrl+V (or Cmd+V on a Mac).
9. Repeat steps 6-8 for all of the remaining pages in your document.
10. Once you've updated the footer on the last page, save your document to make sure all of your changes are applied.

And that's it! By copying and pasting the footer text from your "template" page, you can quickly update the footer on all 30 pages of your document without having to do them individually. Let me know if you have any other questions or if there's anything else I can help you with.
