Not sure about how to get a subtotal of a specific size of page. You get the grand total by default.
This page seems to have the instructions for inserting a link. To summarize, go to Navigation | Edit | Link | Auto Page Links. Scan the area to link. Press Create.
Thanks SLW - sure determination to make it work though from me
I'll have a look at the hatchedit to see why it might not work in other CADS
slight change to the above, see if it works
