A few questions: What version of FM are you using? By deactivate, do you mean all users can see the data in the field but just not modify it?
Usually field protection should be handled by accounts and privileges. This is only guaranteed protection. But you can also use script attached to field (or script trigger) for easier methods (which protect only for specific instance of the field on a specific layout). But we need to know your version and what kind of protections are required. :smileyhappy:
To the first question : I am using FileMaker 10 Pro!
Secondly: Exactly what you emntioned is that what i need: some users to see the field but without the possibility to modify its contents ! except the Admin for sure :smileywink:
Thanks in advance
Do you have a Privilege Set defined for your users? If so, follow this path:
File > Manage > Security… > Privilege Sets > Edit… > Records: Custom privileges… > Field Access [lLimited…] > view only
