The [Full Access] priv set is one of three default privilege sets (the others being [Data Entry Only] and [Read-Only Access]) that come with every database. They cannot be edited. If you want a privilege set different from these, create a new one and edit it to suit your needs.
Instead of selecting 1 of the 3 I selected "New Privilege Set" and now I can edit it. Thanks. I guess I overlooked that setting
Back at scratch cause I was trying to Remove the TOOLBARS in guest mode.
You can't really "remove" the toolbars per se. You can hide them using a script that executes when the user logs in. It might look something like this:
If [ Get ( CurrentPrivilegeSetName ) = "Guest" ]
Show / Hide Toolbars [ Lock ; Hide ]
Set the script to run OnFirstWindowOpen under File > File Options / Script Triggers.
