Are these wires coming from the service panel, or is this a switch loop from an existing ceiling box?

So your BX has Black, Red, White, Green/Bare Copper?

The fan instruction book should tell you which conductor inside the fan housing should be connected to the conductors in your BX to get to your switches on the wall.

Which switch works: The one for the fan, or for the light?

Also did you use a ceiling box and bracing combination rated for fan use?

the 2 wires are coming from an outlet that is in the room. i then added the bx 3 wire that has a black white red and bare wire.
my thinking on this is that the white wire is not working. is there anyway to test this??

There's no need to test anything. What's going on is very clear. The problem is that the white wire that was in the switch box is not a neutral. This is called a "switch loop" and it is impossible to extend the circuit from here without making changes elsewhere.

The only way to get this to work is if you are willing to make the receptacle unswitched. Are you?

Do you remember whether the switch used to control both halves of the receptacle, or only one half?

The next thing to do is to shut off the breaker, gently pull the receptacle out of the box without disconnecting any of the wiring, and tell us everything you see (both the wires connected to the receptacle, and the wires not connected to the receptacle), all the cables and all the connections.

No red wires in the switch box (except the one you added), right?

Let me see if I can restate what you said about the switch box. There are a total of six wires coming into the box: two red, one black, and three white. Is that correct? It seems likely that this is not 100% correct, so I'm looking for more information.

So are these five wires grouped into cables? If so, what's the grouping and please identify the connections again, specifying which wire came from which cable. Also identify what color the screw is on the receptacle where each wire is attached.

ok in the outlet box there is a red wire connected to a brass screw and a white wire connected to a silver screw. now the red wire goes to a wire nut that has 2 black wire and 1 red plus the red wire that goes to the out let. then the white wire that is connected to the silver screw goes back into the wall. also in the box is 2 other white wires that have a wire nut on them.
in the switch box is a 2 wire bx comming up. black and a white. they connect to a slidding dimmer switch. the wire going up to the c-fan is a 3 wire bx plus ground one is red one is white one is black.

You still didn't group these wires for me. Can you tell the wires that enter the box as a group?

Does (or did) the switch also control other receptacles in the same room?

In what city do you live, and in what year was this house built?

This receptacle is incorrectly wired. Do you know if it was wired by a professional?

I suggest you spend $8 on an outlet tester, the kind that plugs in and has three lights on it. I'm pretty sure that it's going to tell you that the receptacle is wired with reverse polarity. (On second thought, it probably has correct polarity, but the switch probably switches the neutral, which is even worse.)

Are there any grounding wires?

All you need to do to make the fan work is (at the receptacle) to connect all three white wires together, and pigtail them with a white wire to a silver screw. But don't turn the breaker back on until we get the switch wired correctly.

At the switch, you'll need to either remove the dimmer and add a duplex switch, or install a larger box and add a second switch to the box. Which do you want to do (or did you already do)?

So on a duplex switch, you'll see that one side has two screws connected by a tab. This is the common side. On the other side are two separated screws. So connect the black wire from the old black/white cable to one of the common screws. Connect the black and red wires from your new cable to the two screws on the other side. Connect the old white wire to the new white wire. Then your fan should work.
