Need help understanding why my motion sensor lights disabled another light?

I have three lights outside, one front door and two on either side of my garage door. I thought I could replace the garage door lights with motion sensor lights, which I did. Now my front door light won't turn on, but the motion sensor lights works just fine. All of these lights are turned on with one switch. Is there an explanation for why this has occurred? If I replace my front door light with a motion sensor light, will it start working or should I buy two new non-motion sensor lights for the garage area and restore the situation back to what it was?

    I would first, check the bulb in the front door. May seem odd but it does happen that they blow sometimes at the same time one is doing work. Then I would recheck the wiring done as well as checking to see if there is a photo cell on that front door that the garage lights may be keeping off.

    Assuming you didn't somehow mess up the wiring, it suggests the problem is in the fixture that doesn't work, perhaps just a failed bulb. All three should have power if the switch is on, so, past the bulb, check for that and go from there.
