Narrative:
Aircraft X stated that he was in the tops at 34000 feet and requested climb to 36000 feet. I was inadvertently looking at aircraft Y's call sign. I climbed aircraft X to 36000 feet. I entered 36000 feet in aircraft Y's datablock; not realizing that I was actually responding to aircraft X. I subsequently shipped aircraft X to sector 37 with 34000 feet still in his datablock as he began his climb to 36000 feet in conflict with aircraft Z eastbound at 35000 feet in my airspace. I noticed aircraft Y's climb and turned aircraft Z 30 degrees to avoid. Aircraft X and aircraft Z passed less than 5 miles apart.this is human error based on inverting callsign numbers.
