Hi.
Do you mean you just want a link to return to top of page? If so forget all of that above!

In BV builder, click "insert" menu, "bookmark". Right click the bookmark that appears, click properties, name the bookmark something like "top". Place it at top of page. Open a text box, type in "Top of Page", or whatever. Highlight and click hyperlink, in hyperlink box, click "bookmark" dropdown, and click on whatever you named your bookmark. Done!
