Attaching blueprint object to skeletal meshes socket

Unless i do not understand childactorcomponent, i do not believe it is what i am looking for.

The Attach Actor To Component node SHOULD work.

My problem is most likely the way i am using/understanding variables.

Attach Actor To component require an "object"Actor and the object with the blueprint is a "object"Blueprint.
I cannot get it to work in the input node of Attach Actor to Component.
