I'm trying to put a halt on a script if the user is not "Administrator", "User 1", or "User 2". My script looks more or less like this:

If ["Users::User Name != "Administrator" xor "User 1" xor "User 2""]

Beep

Show Message ["You don't have access priveliges to perform this action"]

Halt Script

End If

<the rest of the script>

This configuration works, but only if the user name is "Administrator". What am I doing wrong?

You need to make each arguement explicit.

Users::User Name != "Administrator" and

Users::User Name != "User 1" and

Users::User Name != "User 2"

Hmm... It looks like the little crossed out equals sign shows up as "!="

Anyway, it works. I got tripped up on FileMaker's logical operators AND definition:

"AND True only if both items are true"

Because, after all, both items in my case will never be true. Thanks for your help.
