I currently have a box with an empty switch - the top goes to a ceiling fan on the back porch and I hooked the bottom (empty) to a flood light - the problem is when I turn on one - they both come on. Also in the box is a dimmer switch.

The way it's wired: all white wires are connected - the black from the breaker goes to one screw on the top switch (fan) then into a pigtail split to the black for the dimmer and to the bottom switch (flood). The black wire from the fan and flood are on the respective switch - opposite the black from the breaker.

What's wrong with this setup - is it possible for the wiring to be right and the switch to have some sort of jummper?? that would allow current to the fan when the flood switch is on - even with the fan switch off? Please Help!! Thanks in advance!

It sounds like you have a duplex switch. The line side is hooked up the the load side and vice versa, reverse the feed and loads, and see what happens.

A duplex switch has a common screw for power to both switches. Look a atab connecting two screws. The common side usually has 2 screws close together and the switched screws are on the opposite side usually further apart.
