You need Nraas Master Controller to use -any- extra sliders.
So go grab that, then the ones you have should work.
EDIT: And this is specifically how you do it.
I have a number of custom sliders installed, but when I go into CAS I do not see all the sliders, why ?To unlock the ability to have more than the EA Standard number of sliders, you must be running the custom version of CAS provided by MasterController.
By default, custom CAS is only called when you use the "NRaas \ Master Controller" interactions directly.
If you attempt to run CAS from "Edit Town", you are running the EA version of CAS, which does not handle more sliders properly.
You will need to install the Integration module, an optional component of MasterController, to unlock that capability.
Integration will also replace the Shift-Click "Edit Sim in Create A Sim" interaction with custom CAS, allowing you to use that interaction as well.
So you need Nraas Master Controller with the Interactions add on. You can find it easily on the Nraas site. I'm not sure if I'm allowed to link it, so search google for Nraas Master Controller and you'll find everything you need.
