@Dan_in_alabama,
I would start with your wiring setup, it sounds as though you may not have secured all the connections properly. Also, what is the light that you are attempting to control? Ensure that it is within the power specifications of the KS230 and that it uses a compatible dimming type. You can find this information in the User Guides for the KS230Kit
Before Doing anything, however, confirm the hardware version of your device, as the wiring requirements are different between the V1 and V2, with the V2 having interchangeable traveler wires.
Otherwise, can you present a picture of the wiring on the switch and if possible confirm how your two wall plates and light are wired together?
