Private access fields are fields which are placed in a container within the form and are only visible and accessable to the form owner. Main usage is for adding remarks or ratings to entries after they are submitted.
Steps for creating access fields:
1) Enter the form you wish to add access fields to.
2) Drag a container element.
3) Turn on its 'Private Access' checkbox in the element's settings.
3) Drag the elements of your choice in to the container.
4) Save the form.
Access fields will not appear in published forms, only in the form owner's report.
Steps for using the access fields:
1) Enter the form's report page.
2) Double Click on a specific entry line to enter the entry's edit mode (or choose 'Tools'>Edit).
3) Your access fields will now be sowing and you will be able to enter data in them.
