Electrical – Voltage between Red and Copper; and Black an Copper, but not white

I have some 14/3 Romex coming out of the wall. It used to power ceiling fans with a light on different switches (one turned on the light, another the fan). I did some work down circuit and was looking to hook it all back up and am having trouble.

Coming out of the wall I measure 120v AC between the Red and bare copper wire and the black and bare copper wire. I do not read any voltage between the Red and white; and the black and white.

Any ideas?

Update:
I did check for voltage between ground and white. There was none.

The switch for the circuit in question shares location with two other switches. All share a common black (hot) and white. Both of the other two lights work perfect.

This switch was a combo dimmer/switch. I disconnected it and hooked it up, each in turn of the red and black to the hot black. I got no movement from my ceiling fans or lights that are further down the circuit. I am 98% sure they are hooked up correctly at the junction box where I tested earlier.

This is leading me to believe that the wire between the switch box and junction box is bad. While it may be possible that the white wire for this circuit worked its way out of the common tie in for all the whites, I just don't think that is feasible based upon a visual inspection.

Would you all tend to agree?
