You aren't listening.

Did you try this yourself?
From WITHIN FILEMAKER? In a ScriptMaker "perform applescript" step?

It doesn't work.

The fact that you used a tell application "FileMaker Pro" statement suggests
that you are performing this action externally, from Script Editor or
something. Tell statements are not necessary in FileMaker "perform
applescript" script step.
