I want this outlet to be controlled by the dimmer switch and 2nd regular switch. I want the outlet to dim any lamp or rope lighting connected to it to also dim with the other lights. How would i connect the outlet to one of the fixtures in the middle of the run. I installed the 7 recessed lights and the 3way dimmer and regular switch myself and it came out perfect. I just do not know if i should connect the fixture black and white wires to the outlet or use one of the travelers. Is this even possible. Again, i want the outlet to dim with the rest of the lights.

Yes, it’s possible but not recommended. Controlling an outlet with a dimmer switch is not a good idea because someone might plug something into the outlet that could be damaged by dimming power, such as a television. But if you want to do it anyway, you would connect the outlet to the black and white wires at one of the fixtures. And the ground wire of course.
