Floodlight wiring--can't figure it out

[tronnei]

Have a dual floodlight with a motion detector on my deck. Since I disliked the motion detector, I removed it. Now I have black and white wires coming from the house, and two lamps each also with single black and white wires. I figured I should simply connect all three white wires and all three black wires, but that didn't work. How should these wires be connected? (If it matters, the lights are wired to two separate three way switches.)
