Giving permission to enter a field

[sandyinlet]

I've added a script trigger on entry to a specific field. If the user does not have permission to edit, they're provided with a dialogue and can't enter. However if they do have permission the field is selected and then exited. How do I let authorized users remain in the field and continue editing?

Here's the code:

If [ Get (ScriptResult ) = Null ]

Show Custom Dialogue ["No permission to edit!"]

Halt Script

End If

Much appreciated.

Why do you need a script trigger, or a script at all? If they are not authorized to edit the field, they will get an error message as soon as they try to.
