A little confused here...are you interested in using the offpage connector shape?
You need to do a few steps that are indicated in the referenced post...
1.) Drop an offpage connector onto your page and delete it. This creates a master in the document stencil. Note, this is only available in the current document. After editing, you could save the modified mastershape to a custom stencil, and then it would be available for other documents.
2.) Then edit this master to Match name on drop and to sync the text as described.
3.) Now, edit the master shape's shapesheet:
a.) Add User Defined section
b.) Add new row and give it a catchy name, or not, like user.EqPageName.
c.) In the value cell, enter pagename().
d.) Add Hyperlink section
e.) Change row name to Hyperlink.OffPageConnector. This is critical, because when you create an offpage reference, the code will generate this row. But, this row must pre-exist in order to make a valid field insert below.
4.) Go back to the master shape drawing page, and then Insert>Field>Custom. Enter the following formula, using whatever name you used in 3b above: User.EqPageName&CHAR(10)&Hyperlink.OffPageConnector.SubAddress
Close the shapesheet, close and save the master shape drawing page.
Explanation:
The formula will show two entries: 1st, the current page and 2nd the linked pagename. if you don't want the current page name, just delete the User.EqPageName&char(10)&, keeping only the hyperlink info.
This only works because of the built-in functionality of the offpage connector. Hopefully, I have all of the steps, and have them correctly indicated.
