You may have to scroll down to see it, as it's always at the bottom of the list.
4. Under Layout, select the “modifiable” radio button .
Turning this setting on tells FileMaker you want new layouts to be modifiable. Click
OK when you're done. See Figure 18-10 to see the warning you'll get if you forget
this option.
Figure 18-10. If you select “Allow creation of new layouts” without making new layouts modifi-
able, then FileMaker complains that it doesn't make sense to let someone make a new layout she
can't edit. You can't close the window until the privileges do match one another. Either turn off
“Allow creation of new layouts” or make [Any New Layout] modifiable.
Now, anybody with the Project Manager privilege set can edit any new layouts she creates.
Value list privileges . Value lists may not seem as critical a security choice as records and
layouts, but since value lists help people enter consistent data, you want to pay attention to
these choices. If you put a pop-up menu on a field to limit data input, but then you give those
same people the ability to modify the value list underlying the pop-up menu, then they have
a way to circumvent your control.
You can see the Custom Value List Privileges window in Figure 18-11 . This window lets you
assign any of three privileges to each value list: modifiable, view only, or no access. You can
also let somebody create new value lists with an “Allow creation of new value lists” check-
box, and set the privileges to be assigned to any new value lists.
You can control access to value lists in much the same way you manage record and layout
privileges. And like record and layout privileges, you have three canned choices in the pop-
up menu, plus Custom privileges:
▪ All modifiable means people can use and edit every value list.
▪ All view only lets people only see and select from your value lists, but not change them.
▪ All no access prevents people from seeing value lists at all.
▪ Custom privileges gives you a dialog box where you can create your own set of priv-
ileges.
