Individual XYZ Rotation for Instanced Hierarchical Static Mesh?

Hey everyone!

I’m hoping someone on here could please help with a project of mine. I was wondering how to have each hierarchical instanced static mesh in a BP have its own random rotation? I’ve included a screenshot of my BP along with a simulation.

I’m not sure what I’m doing wrong that makes my instanced static meshes stand the way they do as pictured. There is no rotation or movement, they just stay idle.

Thanks everyone in advance for the help, I really appreciate it!
