After upgrading from Formulator 2.5 to 3.0 you may wish to combine several single-page forms into one multi-page form. To do so follow these steps:
Open the single-page forms in Edit Zones mode and use Form / Save Image… to save the image of each form. Keep the forms open.
Create a new multi-page form without a form image.
Go to one page after the other and open the corresponding image using Form / Open Image….
To copy the zones open the corresponding single-page form, select Edit/ Select All and Edit / Copy. Then, change back to the multi-page form go to the corresponding page and insert the zones. While the zones are still selected move them to their correct positions.
