How do I ADD more rows to Item C of the SF330 Part I?

Download and save this page to the proper "Forms Folder" defined under Preferences in the GFS software program:
(2).AC.330

Refresh [F5] the list of available forms in the File Tree. This new form should be listed under Section A-C.

Open that form, right-click and Copy Page. To add it to another form, move to Page 2, right-click and select Paste Page.

If the page is not inserted in the correct location you can right-click again and use the Move Page command, either Forward or Back.
