I've been setting up users and groups for the first time, and something seems to have sprung a leak. Initially, I set assigned each user to one or two groups, and all worked fine. For example: group A read-only + group B none = read-only. Unfortunately, I added two other groups for a number of users. They are now set up as: group A read-only, groups B-D none. Since that happened, these users have FULL access to the form. What am I doing wrong? Any help would be greatly appreciated.
