base isn't of much use. If someone were to open the database with this privilege set now,
she'd see something like Figure 18-8 .
FileMaker uses layouts to display your file's data, which means you need to add layout ac-
cess to your privilege sets. To give people all-important access to the various database lay-
outs, use the Edit Privilege Set window's Layouts pop-up menu:
▪ All modifiable means people can use and edit every layout. (Here, “edit” means “Add
fields, delete portals, resize parts, and generally manipulate objects on layouts.”)
▪ All view only gives people access to data on every layout but doesn't let them change the
layouts themselves.
▪ All no access prevents any layouts from showing, as shown in Figure 18-8 .
Figure 18-8. When people try to view a layout they don't have access to, this blank screen is what
they see. FileMaker tries hard to avoid this situation, though; if you haven't already removed the
layouts the user can't access from the Layouts pop-up menu, it removes them for you. But your
scripts can still put users somewhere they don't belong. And in this case, they don't have access to
any layout, so FileMaker doesn't have much choice but to show this message.
The final option—Custom Privilege—lets you exercise the greatest control over access to
specific layouts. Since layouts are a vehicle for the other database items on the layout, you
have two distinct layers of privilege:
▪ Layout . These privileges control people's ability to view or edit the layout itself. They're
basically the same as the All layout privileges described above, but they apply only to the
selected layout. Choose modifiable if you want to let people edit the layout (enter Layout
mode and then move fields and things around), view only if you want them to only see it,
