dual light switch


I am replacing a light fixture that is run on a dual light switch. Out of the electical box were 2 white wires that are twisted together, a black wire and a grounding wire. I hooked up the fixture, white to white, black to black and ground to gtround. The issue is now the dual light switches operate independantly. In other words, the top switch will turn the fixture off and on, the lower switch will turn the fixture on and off but if I turn the light on with the top switch, I cannot turn it off with the lower switch

Are you sure it ever worked like that?
A dual switch it used to control 2 loads from the same supply.

What do you mean by dual light switch? Do you mean a three way switch? A three way switch setup would be one switch at one side of a room and another switch at the other side with both switches controlling the same light.

I guess I do mean a 3 way switch, 2 switches at either end of the hall work one light

This makes sense now.
In your first posting:

Is this the box where the old fixture was attached? Is this how the wiring was before you touched anything? Things don't add up. You have two white wires but only one black and one ground. You'd better take another close look inside that box.

The original fixture was wired 33 years ago and the original fixture was connected to the 2 white wires Oops there are 3 white wires , the black wire and the grounding wire. There are additional wires inside of the electrical box, but they were not connected to the light fixture we took down. Why would both switches work the fixture (only not together), could it be the light switch also

Somehow you didn't connect the new fixture to the same wire configuration that was used with the original fixture. I'd guess that two of the wires are part of the travelers that run between the two switches.
