Hi
Try the following:
1. Set up your Bookmark in an adjacent cell and enter some text.
2. Select another cell.
3. Select Insert Tab - Quick Parts - Field.
4. In the left hand column scroll down and click on "Ref".
5. In the right hand column click on the Bookmark name.
6. Click OK.
The bookmark text will now be repeated in the active cell.
Hope this is what you were looking for.
Good luck.
Tony
