Using this YouTube tutorial I created a Table of Contents in a document. Everything seems to work just fine on the MSOffice 2016 originating Windows 10 Pro (up to date) PC. Opening the document in another PC, also with MSOffice 2016 and Windows 10 Pro, leads to the Table of Contents and the multi-placed button in the document, not working at all.

1. While making the document and following the tutorial I found that all I had to do was hover over the ToC, click, and I would be taken to various Heading 1, 2, 3, or 4 locations. Thus the rest of the tutorial is not really followed as far as copying/pasting/linking Headings to make a ToC.
2. I created a button that takes me from any location in the document back up to the ToC. I have placed that button in many document locations.
3. However, the button, when clicking on it, goes into an editable object. I cannot figure out how to make it static
4. I also have not found a way to make the button move with document added/deleted/edited text. The option to change the button behind, in front, inline, etc does not seem to address my issue
5. Nonetheless, my biggest concern is getting the ToC to work on PC's other than the original PC where the document was created.

I have used WORD for 25+ years but am definitely not an expert. I must be doing something wrong.

I sure would like some help to correct my errors.

Thanks, Dekade
