Setting multiple switches on a single sound in UE4 Blueprints [closed]

Question

Hello

I'm setting up a speech system that aims to allow triggering of multiple different contexts with just one event, using switches.

When I set this up in my UE4 Blueprint, I can get the sound to trigger if only one switch is set. But if I try to set two switches, it fails to play.

I've uploaded pics of the sound hierarchy, event and blueprint here: https://imgur.com/a/xEKZlS0

Any ideas where I'm going wrong?

Thanks!
