VRCMirror Toggle Help

Been following along with Iconoclass’s tutorial, but my toggles don’t actually turn the mirrors on and off like they’re supposed to. I’ve re-followed the steps 4 times now and it’s still not working.
Below are screenshots of my setup. Please point out what I’ve set up incorrectly, because I’m stumped!



Thanks in advance, everyone! ^^

For context, I want the mirrors to be OFF until a player clicks to toggle them on.
Here’s what it looks like when I spawn in Client Simulator:


and here’s what it looks like when I press a toggle:

both mirrors are ON when I spawn in and are unaffected by the toggles

BTW! I also tried following this from the comments section, but it didn’t resolve my issue.
