2 singles poles controlling 2 lights, changing one for a dimmer

Hello everyone!

I am trying to replace a single pole switch for a dimmer (which is a 3 way). After following the setup instructions, the single pole which is still there still control its light. The problem is the dimmer, which when turned on, turn off the other powered on light and the dimmer turn on its own light. When I turn the dimmer off, the other light turns back on (while the single pole switch is on).

Any idea what is happening? Is it possible I just can't install a dimmer?
Help please! Thank you in advance.

How many wires were connected to the original switch?

3 wires, 2 black and one red. One of the black is the hot wire. The box where the dimmer is contains 2 sets of wires. One set have a black (hot), red and white wire, the other have only a black and a white wire.

Edit : Here are the pictures of the 2 switches.

I fixed your pictures.

In the first picture is a single pole switch serving as a switch loop only. (nothing to do with the second picture)

The second picture shows a two wire cable and a three wire cable in the box. Is there a match to that switch ? A three way circuit has two three way switches.

I'm going to take a shot that you don't actually have a three way circuit and that you are trying to use a three way dimmer on a single switch circuit. If that is the case.... you would connect both black wires together and then to the common wire of the dimmer. The red wire goes to one of the traveler wire on the dimmer and the other traveler wire from the dimmer gets capped off.

I agree with PJ after seeing the pictures. As I suspected, you mis-connected a wire carrying power to another part of the circuit to a traveler.

I know nothing about home electricity so it is very probable that I bought the wrong dimmer ! Just to be sure, what do you mean by "the other traveler wire from the dimmer gets capped off " ? To tape it, use wire nuts or something else?

I'm going to try your suggestions as soon as possible !
