Locking portal fields

[Jimjmn]

I have a DB that has a button on a layout that enables the user to lock/unlock a record. I am executing this by having the button change a field call "lock" from 1 to 0 and in custom privileges the user is locked out if the field contains "0." The problem is that I have portals on the same layout and I'm unable to lock them out. How might I go about this? I know that I could lock these fields from the custom privileges but I would also like to be able to lock these fields on their own layout as well.

Did you consider having the lock button switch to an identical layout on which the fields are set to not allow data entry?

I know of this option but is there no other way?

Script must set the lock field in the related records to 0 as well. Make sure users cannot reverse this action by tampering with the lock field.
