[HELP] Filter damage to actor1 while actor2 is alive

Good Morning/Afternoon,

I’m trying to create an expression where on the below link, I can see damage to Loyal Myrmidon while Lady Venomtongue and Serena Scarscale are alive (not both, but if either is alive - They could die in any order in my guild).

https://www.warcraftlogs.com/reports/jV2fg4NktKMnDBAx#boss=-2&difficulty=0&wipes=1&type=damage-done

The idea is that I get to see who is damaging the Myrmidon, whilst the priority targets, the two casters who sit on the wards are alive.

I’ve previously tried the likes of:

target.name = “Lady Venomtongue+Serena Scarscale” and resources.hitPoints > 0

and then setting the damage done page to Loyal Myrmidon, but that throws up no damage

Your advice and input would be most helpful
