you should call an electrician.

You need to tell us all the wire connections in the existing light switches and existing light box. Then tell use what cable you are going to run from the new light to which switch.

the switch I wanna use has black,red,white the common is white the same color also goes for the other switch. the lamp has blk and white also the green for negative

There is no positive and negative in housewiring.

The green wire is not the negative, it is the ground wire. It should not be connected to the screw shell of the light. It should be connected to any other metal parts of the light fixture and any metal boxes etc.

You need to answer joed's question in much more detail before we can help you. Start with switch box A and tell us all the wires and connections in there. Next tell us about switch box B and third tell us about the light fixture.

We may have more questions after the above are answered.

You don't have enough wires. Three wires at each switch and two wires at the light is not enough to make it work. You need at least one more cable (two wires) for a power source.

Why r u removing the 2nd switch on the 3 way the 1rst will still control the new fixture irregardless of #2?

Ok the switch I wanna use only has 4 wires in the box red,white,blk,copper. the box that I want to continue to use has 2 switches in it. 1 for the car port light and the other to control the light in the dining room. the switch for the carport has a red,blk,whte and copper the switch for the othr one one has a red,whte,blk,copper.That is all the wires in there. the light i am going to use has 5 blk and 5 white. Which i tie all blk' s together except 1 and all whte except one. Also a green wire with a screw on it that attaches to the base of the light that is all

You also need to know the wiring going to the existing light box itself to confirm how the 3 way is confirgured, there's a few way to wire up a 3 way system... but I would recommend you call an electrician as well...
