Narrative:

The problem arose when I decided to descend aircraft #1 to FL240 and climb aircraft #2 to FL390, when they were on conflicting paths. Aircraft #1 needed to cross lvz at FL190. After giving the 2 clrncs, I determined that a conflict would occur. I turned aircraft #1 to a 080 degree heading. I turned aircraft #2 approximately 30 degrees left. Before where I believed I would lose separation, I asked aircraft #1 to verify leaving FL265 which was replied as affirmative. I asked aircraft #2 to verify leaving FL275 and heard 'yeah.' after hearing yeah, I tried to enter reports. Upon reflection, I don't know if yeah was an appropriate report in this instance.
