This action cannot be performed because this file is not modifiable
I am trying to share a database that is stored on my iMac over a LAN. The other users can see and search the database. They can do everything except edit the database.
Every time they try to make any changes a message "This action cannot be performed because this file is not modifiable" comes up.
I have gone through all the "Manage Accounts and Privileges" settings and "Sharing Filemaker Network" settings I can find in the users guide and the help files, and I still get the same message!
What am I missing?
