Narrative:
Were given instructions to cross luvs intersection at 6000 ft. We were descending through 6300 ft and the TCASII told us to climb to avoid traffic at 5500 ft. I began to start climbing, but there was also traffic at 6500 ft, so I started to descend again and reached 6000 ft. Center was pointing out traffic at 6500 ft. I'm not sure how close we were to the 6500 ft traffic.
