Destroy Destructible Mesh Through Trigger

I’ve updated it a bit with what I think is required.

However, damage is still not being done to the destructible. I’ve set up a print string to check this, and it doesn’t fire, even though the rest of the blueprint is apparently functioning. Have I somehow set the wrong target? Is it possibly because a blueprint can’t damage itself? I’m totally lost.
