I am a bit confused
It’s RTM it’s early release but I’m not sure if you should use it I have found a nasty little bug.
Can’t pass variable/parameter in nested modules/component (PSU 2.12 and PSU 3.0) · Issue #1225 · ironmansoftware/issues (github.com)
thanks, I wait a bit 
I’m going to roll back a change we made to Show-UDModal. This affects 2.12.0 as well. I was attempting to fix a different issue and it’s causing this problem.
