I did as you said and you were correct. I connected the black dimmer switch wire to the black Romex wire going to the light. I connected the solid red to the black jumper going to the switch on the right. Thank you so much for the help.

Yes, one is for track lighting in the living room and the second switch is for the main kitchen light. It threw me off with all the white wires tied together and all the ground wires tied together, but none of them connected to the switches.

Hey, thanks for the reply. I have a meter. I've wired some things before, but I always had the hot, ground, and neutral. It threw me off that none of the white or ground wires were connected to the switches. So, I tied the incoming black wire to the black on the dimmer switch, the ground to the other grounds, the solid red to the jumper going to the second switch, and capped off the red striped wire.
