Expanding tables with calculating form fields?

[macropod]

Re:
1. You could select a given formfield and delete the contents or reset the dropdown value to the default. Added dropdown items and the 'lbs' fields for them can't be removed this way, though. In any event, if you save the document as a template, only the default setup will appear in any new document.
2. Not without devising some means of adding some 'remove rows' code that you could trigger somehow.
3. No. That said, I've coded the macro attached to the Nomenclature dropdown so that two more items can be added. The alternative would be to re-write the document using content controls.
