Class Archetype Error - no levels in Kineticist for abilities

[Mediator9292]

I'm creating a Swashbuckler archetype that utilizes Kineticist abilities, but I can't figure out how to make it register levels in Swashbuckler as partial levels in Kineticist. All of the Kineticist abilities are showing similar error messages - that they require levels in Kineticist to be valid. I've tried expr-reqs like, "#custspeciallevelcount[Kineticis *and Swashbuck*] = #totallevelcount[]/2", "#totallevelcount[Kineticis] = #totallevelcount[Swashbuck]/2", and "#custspeciallevelcount[Kineticis *and Swashbuck*] = 10", but I still can't get it to register anything, if it even works at all. Does anybody have any suggestions?
