Flipping Layered Images

[Chendzeea]

I'm trying to make my character images flip when using the "at right" command. I was using xzoom -1 each time but that was tedious. So I figured I'd make a If statement that I can toggle as needed. However I keep getting this error. Suggestions?

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.
